The Odd Couple II is a 1998 American buddy comedy film and the sequel to the 1968 film The Odd Couple. It is the final film written and produced by Neil Simon, starring Jack Lemmon and Walter Matthau.

It has been 17 years since Oscar Madison and Felix Ungar have seen each other. Oscar is still hosting a regular poker game and is still an untidy slob, now living in Sarasota, Florida, and he is still a sportswriter. One day, his son Bruce calls with an invitation to California for his wedding the following Sunday. A second shock for Oscar—the woman who his son is marrying is Felix’s daughter Hannah.
