Since the hit NBC sitcom wrapped in 1998, the cast has starred in blockbuster movies, hit Broadway plays and Emmy-winning series
NEED TO KNOW
- Seinfeld premiered in 1989 and ended its nine-season run in 1998
- Jerry Seinfeld — who co-created the series with comedian and guest star Larry David — led the series alongside Julia Louis-Dreyfus, Jason Alexander and Michael Richards
- The NBC sitcom won 10 Emmys and three Golden Globes during its tenure
Seinfeld, the “show about nothing,” made the mundane funny across nine seasons.
The pilot episode of the legendary sitcom premiered on NBC on July 5, 1989, changing television by focusing on everyday — often absurd — occurrences instead of tantalizing drama, serial plots or episodic story arcs.
Its core cast included the close-knit group of four sardonic friends in New York City: Jerry Seinfeld — a character that’s just a slightly fictionalized version of Seinfeld himself — and his friends Elaine (Julia Louis-Dreyfus), George (Jason Alexander) and Kramer (Michael Richards). Larry David, who co-created the hit with Seinfeld, also appeared on the series, taking on various silly roles like the voice of George’s boss and a cape-wearing lawyer.
The show ran for almost a decade, concluding (controversially) with its series finale on May 14, 1998. Throughout its run, Seinfeld earned 10 Emmy Awards and three Golden Globes.
Since then, the cast of Seinfeld has continued to flex their comedic chops, acting on and producing hit shows like Veep and Curb Your Enthusiasm and racking up film credits.
“Yada, Yada, Yada!” Here’s everything to know about the cast of Seinfeld now.
01 of 10
Jerry Seinfeld as Jerry Seinfeld
Seinfeld played a version of himself on the sitcom, starring as a mildly famous stand-up comedian who performed in comedy clubs around N.Y.C. He was a perennial bachelor with a loving but very eccentric group of friends.
After the show ended in 1998, Seinfeld worked on various projects, including his first major film, 2007’s Bee Movie, in which he voiced the main animated character, co-wrote the script and served as a producer. The movie became a hit, grossing over $293 million. In 2024, he made his directorial debut with Netflix’s Unfrosted.
Seinfeld started his own talk show, Comedians in Cars Getting Coffee, in 2012, where he picked up his comedian friends in various cool vintage cars and drove around, talking about show business and their personal lives. The show ran for 11 seasons, ending in 2019, and featured tons of stars, from Tina Fey to Barack Obama.
He’s also made several cameos on TV shows over the years, including on Curb Your Enthusiasm. In addition to popping up on David’s HBO show, the duo had a rare reunion with Louis-Dreyfus on Christmas Eve in 2025.
Seinfeld has been married to his wife Jessica Seinfeld since December 1999. They share three children: daughter Sascha Betty and sons Julian Kal and Shepherd Kellen.

Julia Louis-Dreyfus as Elaine Benes
Louis-Dreyfus starred as Elaine Benes, Seinfeld’s ex-girlfriend-turned-close friend. The role landed the actress seven consecutive Emmy nominations between 1992 and 1998; she won Outstanding Supporting Actress in a Comedy Series in 1996.
She told PEOPLE in May 2023 that “there was a real grief period when the show ended that was real and felt because we all loved each other so much.”
“I wanted to keep working. I wanted to keep doing this thing called acting,” Louis-Dreyfus continued. “I wanted to keep pursuing it, which I’ve been able to do, which is great.”
Her career has flourished since her time on Seinfeld. Not only has she returned to SNL numerous times, but she’s also had recurring roles on sitcoms like Curb Your Enthusiasm, The Simpsons and Arrested Development, as well as starred on The New Adventures of Old Christine.
However, Louis-Dreyfus’ true post-Seinfeld showstopper was the smash success Veep, where she played the floundering Selina Meyer, the American vice president constantly mired in hilarious setbacks and scandals. Over its seven-season run, the HBO series was nominated for a whopping 68 Emmys, with Louis-Dreyfus scoring an impressive 14 nods and ultimately winning nine times for both acting and producing.
Her post-Veep credits include the 2023 films You People, You Hurt My Feelings and Tuesday. Louis-Dreyfus joined the Marvel Cinematic Universe (MCU) portraying Valentina Allegra de Fontaine in several MCU films, including Black Panther: Wakanda Forever (2022) and Thunderbolts* (2025). In 2026, she lent her voice to the ewe character Lily in The Sheep Detectives and Midge in Tangles, which she also produced.
In her personal life, Louis-Dreyfus has been married to actor and comedian Brad Hall since June 1987. The couple share two sons, Henry and Charlie Hall, both of whom are actors. Charlie has appeared on Single Drunk Female and The Sex Lives of College Girls and will star on season 4 of The White Lotus, while Henry, who is also a musician, appeared on White House Plumbers.

Jason Alexander as George Costanza
Alexander played George Costanza, Jerry’s good friend who often got into relationships ... and then was dumped soon after.
In September 2022, Alexander was a guest on Today, where former co-host Hoda Kotb and Jenna Bush Hager asked the actor what continues to make Seinfeld so relatable and popular, to which Alexander responded, “Jerry [Seinfeld] and Larry [David] had an ethic about it that said if it’s funny, it’s good ... funny reigned supreme.”
He added, “What was funny then is somehow still funny now, and people are just watching it to laugh.”
Since the show ended, Alexander has had recurring roles on shows like Curb Your Enthusiasm, The Conners, Young Sheldon and The Marvelous Mrs. Maisel. The Emmy-nominated actor also appeared in 2001’s Shallow Hal and 2025’s The Electric State.
He’s also voiced multiple animated characters. Best known for The Hunchback of Notre Dame, which was released during Seinfeld‘s run in 1996, he can also be heard on The Tom and Jerry Show, American Dad! and Mating Season, among many other series.
In addition to his roles on the small screen, Alexander is a prominent figure in the theater world. He’s starred in hit plays and musicals like Merrily We Roll Along, The Producers and Fish in the Dark, and directed productions such as The Cottage.
Off-screen, Alexander has been married to actress and artist Daena Title since May 1982. The couple have two adult children, sons Noah and Gabe.

Michael Richards as Cosmo Kramer
Richards played the iconic Cosmo Kramer, better known simply as Kramer. Kramer was the neighbor across the hall who always ended up in Jerry’s apartment. The character was inspired by co-creator David’s real neighbor, stand-up comedian Kenny Kramer.
After his time on Seinfeld, Richards continued to perform stand-up. He had a few minor roles, appearing on Curb Your Enthusiasm a handful of times in 2009 and landing a recurring part on Kirstie Alley‘s short-lived sitcom Kirstie.
However, he largely left Hollywood following a 2006 “racist rant” at the Laugh Factory in L.A.
“Anger had a hold of me, and I canceled myself out,” he told Kotb in a rare TV interview on Today in June 2024. “Take an exodus. Get away from show business and see what the heck was going on inside of me to be so despicable that night, losing my cool and hurting.”
The Emmy winner returned to acting in the 2019 film Faith, Hope & Love. In 2024, he released a memoir, Entrances and Exits.
Richards has a daughter, Sophia, with ex-wife Cathleen Lyons, whom he divorced in 1992 after 18 years of marriage. In 2010, he married actress Beth Skipp. Together, they have one child, son Antonio.

Wayne Knight as Newman
Despite being only a supporting character, Wayne Knight’s Newman remains one of the most iconic from the series. Newman lived down the hall from Jerry, and the two often butted heads, worsened by Newman’s participation in Kramer’s wild schemes.
After Seinfeld concluded, the Georgia-raised actor continued to star on series like Hot in Cleveland and The Exes, while nabbing guest spots on That ‘90s Show, 9-1-1: Lone Star, Bookie and St. Denis Medical.
In addition to appearing in 2016’s Hail, Ceaser! and 2025’s Five Nights at Freddy’s 2, Knight has voiced characters in the Kung Fu Panda franchise, the 2026 film GOAT and on series like The Penguins of Madagascar, Harley Quinn and Among Us.
Knight married makeup artist Paula Sutor in a May 1996 ceremony at former Seinfeld costar Richards’ house. The couple divorced by December 2003, and he wed film editor Clare Knight three years later in October 2006. They went on to welcome one child together, son Liam.

Jerry Stiller as Frank Costanza
Jerry Stiller starred as George’s cantankerous father Frank. Audiences can thank Frank for popularizing Seinfeld’s version of Festivus, a holiday “for the rest of us,” as he would say.
Born and raised in N.Y.C., Jerry was perfect for the role of a well-seasoned New Yorker who’s seen it all, but his career began long before Seinfeld. In September 1954, he married fellow comedian and performer Anne Meara, and together they performed as the comedy duo Stiller & Meara throughout the ‘60s. Jerry also appeared on The Mike Douglas Show and Johnny Carson‘s The Tonight Show and also had roles in hit films like Airport 1975 and both Hairspray movies.
The same year Seinfeld ended, Jerry landed another role as a father in a sitcom, portraying Arthur Spooner on the hit The King of Queens, which ran from 1998 to 2007.
Jerry and Meara had two children who followed in their footsteps: daughter Amy Stiller and son Ben Stiller. Jerry appeared in five films with Ben, including Hot Pursuit (1987), Heavyweights (1995), Zoolander (2001), The Heartbreak Kid (2007) and Zoolander 2 (2016).
The Zoolander sequel was the actor’s final on-screen performance before his death from natural causes in May 2020 at age 92. Ben directed and released the documentary Stiller & Meara: Nothing Is Lost in 2025, covering his parents’ lives and the funny duo’s legacy.

Estelle Harris as Estelle Costanza
Estelle Harris played Estelle Costanza, the loud and quick-witted mom to George and wife to Frank, who was always full of hilarious one-liners.
After the sitcom, Harris became best known as a voice actor, most notably taking on the role of Mrs. Potato Head in the Toy Story franchise — 2019’s Toy Story 4 was her final role — as well as characters on shows like Dave the Barbarian, Fanboy and Chum Chum and Jake and the Never Land Pirates. She also appeared on the Disney Channel series The Suite Life of Zack and Cody.
In 1953, she married Sy Harris. The pair shared three children — Eric, Glen and Taryn — and they were together until Sy’s death in January 2021.
Harris died from natural causes in April 2022. She was 93.
The day after her death, Alexander, who played Harris’ on-screen son on Seinfeld, paid tribute to the actress on X, writing, “One of my favorite people has passed - my tv mama, Estelle Harris. The joy of playing with her and relishing her glorious laughter was a treat. I adore you, Estelle. Love to your family. Serenity now and always.”

Barney Martin as Morty Seinfeld
Barney Martin played Jerry’s father, Morty Seinfeld, who made a living selling raincoats. He also invented a beltless trench coat he called “The Executive,” which played a prominent role on one of Seinfeld’s iconic two-part episodes.
Martin was born in Queens, N.Y. According to his obituary in The New York Times, he pursued many careers throughout his life. Before joining the entertainment industry, he served in the Navy during World War II and later became a detective.
His first big break in entertainment came in 1967 when he starred in Mel Brooks‘ The Producers, and he originated the role of Amos Hart in the musical Chicago. Martin went on to appear on several series before landing his role on Seinfeld, including Night Court, Punky Brewster and 21 Jump Street.
Following Seinfeld, he had a handful of roles, with his last credit coming on John Goodman‘s short-lived CBS sitcom Center of the Universe.
Martin died of cancer in March 2005. He was 82.

Liz Sheridan as Helen Seinfeld
Liz Sheridan played Jerry’s mom, Helen Seinfeld. The character loved her son more than anything, as shown with her incessant nagging.
After the show, she appeared in 2002’s Now You Know and 2009’s Play the Game and guest-starred on Numb3rs and American Dad!. Her final on-screen acting credit was the 2010 film Trim.
The New York native also had an impressive theater career, starring in 12 Broadway shows over the years, including Happy End alongside Meryl Streep, and performing a one-woman show titled Mrs. Seinfeld Sings.
In 2000, she released a memoir, Dizzy & Jimmy: My Life with James Dean. The title came from Sheridan’s nickname “Dizzy,” and the book recounted her relationship with late actor James Dean, who died at 24 in 1955.
Sheridan died in her sleep of natural causes in April 2022. She was 93. Seinfeld paid tribute to his on-screen mom on X, writing, “Liz was always the sweetest, nicest TV mom a son could wish for. Every time she came on our show it was the coziest feeling for me. So lucky to have known her.”

Larry David as Various Characters
David co-created the original idea for Seinfeld and served as a writer, producer and actor throughout its tenure. He appeared on the show several times, including as a passenger on an airplane, a TV character and a pedestrian. However, he’s best known for voicing George’s boss, George Steinbrenner, based on the real-life New York Yankees owner.
Since his time on the show, the Brooklyn-born star has become best known for his HBO comedy Curb Your Enthusiasm. The series premiered in October 2000 and ran for 12 seasons, concluding in April 2024.
David also popped up frequently on SNL — he hosted the show twice in 2016 and 2017 and regularly portrayed Bernie Sanders in various sketches. (He had been a writer on the sketch show’s 10th season, which is where he met Louis-Dreyfus.)
Off-screen, David is married to producer Ashley Underwood. The two met in 2017 at a birthday party for actor Sacha Baron Cohen and married in October 2020. David has two daughters, Cazzie David and Romy David, whom he shares with ex-wife Laurie David.
