Seinfeld is one of the most critically acclaimed and highest-rated sitcoms of all time, with characters Jerry, Elaine, George, and Kramer forever etched into the heart of pop culture. The series follows the life of comedian Jerry Seinfeld and the antics of his group of friends which consists of his ex-girlfriend Elaine, best friend George and wacky neighbor Kramer.
When Seinfeld ended in 1998, the cast went their separate ways, each carving out their own unique niche in the entertainment industry. Some were said to have fallen victim to the so-called “Seinfeld curse,” while others found success. Jerry Seinfeld even went on to become a billionaire. But where is the Seinfeld cast in 2025, and what are they doing? Let’s find out.

1. Jerry Seinfeld (Played Himself)
Jerry Seinfeld played a fictionalized version of himself on the show as a stand-up comedian who mainly did observational humor and was at the center of his friend group.

One of his main traits in the show is breaking up with his girlfriends over small reasons.
Jerry immediately returned to stand-up after Seinfeld ended and has since then made more comedy shows like Comedians in Cars Getting Coffee where he invited celebrities, drove them around the city, grabbed some coffee, and cracked jokes. It was widely popular with both fans and critics alike.
In 2020, Jerry Seinfeld dropped 23 Hours to Kill on Netflix, which was a hit among fans.
