Who is Frank Costanza?
Frank Costanza is George's father, a man of tremendous passion, volcanic temper, and a gift for fixating on perceived slights with extraordinary intensity. Played by Jerry Stiller from Season 5 onwards, Frank is one of Seinfeld's greatest recurring characters — an explosion waiting to happen who arrives in scenes and immediately raises the energy of everything around him.
Frank is a Korean War veteran, former military cook, and the patriarch of the Costanza family in Queens. He and his wife Estelle exist in a permanent state of low-grade domestic warfare, arguing about everything from sleeping arrangements to the memory of a dinner party decades in the past. Their relationship is catastrophic and entirely codependent.
Festivus
Frank Costanza's most enduring contribution to popular culture is Festivus — the secular holiday he invented as an alternative to the commercialisation of Christmas. Celebrated on December 23rd, Festivus centres on an undecorated aluminium pole, the Airing of Grievances (during which Frank tells his family all the ways they have disappointed him over the past year), and the Feats of Strength (a wrestling match that ends the celebration).
Frank invented Festivus after a fight over a doll at Christmas led him to question the entire holiday. "I find tinsel distracting," he explains. "Many Christmases ago, I went to get a doll for my son. I reached for the last one they had, but so did another man. As I rained blows upon him, I realised there had to be another way." Festivus has since entered real-world use, celebrated annually by fans worldwide.
The Mansiere
Frank's other great invention is the Mansiere — a brassiere for men, conceived after he noticed that men's chest areas needed the same support offered to women. He develops the concept with Kramer as his business partner, though the two disagree on the name: Kramer prefers "the Bro." The Mansiere storyline in "The Doorman" is one of the show's finest Frank moments, featuring Jerry Stiller at his most committed.
Legacy
Jerry Stiller's Frank Costanza is a character of almost operatic intensity — every line delivered as if the fate of the world depends on it. Stiller brought a physicality and commitment to the role that made Frank unpredictable and magnetic in every scene. The character appears in 26 episodes and remains one of the most beloved recurring presences in the show's history.

Did You Know?
1
Festivus is based on a real holiday invented by writer Dan O'Keefe's father Daniel O'Keefe Sr. in 1966. Dan O'Keefe pitched it to the Seinfeld writers and the details were changed significantly — the original Festivus had very different traditions including a clock in a bag.
2
Frank Costanza was played by a different actor — John Randolph — in his first appearance in Season 4's 'The Handicap Spot.' Jerry Stiller took over from Season 5 and the Season 4 episode was re-shot with Stiller for syndication.
3
Jerry Stiller is the father of actor Ben Stiller, who directed several episodes of Seinfeld and appeared in two episodes as George's romantic rival.
4
The phrase 'Serenity now' was actually used by Lloyd Braun in the episode, not Frank — though Frank is associated with it because he taught it to George as an anger management technique.
5
Festivus is now celebrated by thousands of people worldwide on December 23rd each year. Several US state legislatures have passed resolutions recognising it, and Festivus poles have been erected in public spaces.
6
Frank's Korean War backstory — particularly the traumatic cooking incident that he never fully explains — was a recurring mystery that the writers used to justify his extreme personality without ever resolving.
7
Jerry Stiller was in his late 60s when he began playing Frank Costanza. He had been primarily known as a stand-up comedian before the role made him a television star.
8
The Mansiere, Frank and Kramer's invention of a bra for men, was not entirely fictional — similar products exist and are sold under various names.
