Half & Half is an American television sitcom created by Jeffrey Klarik that aired on UPN from September 23, 2002, to May 15, 2006. The show focuses on the lives of two paternal half-sisters in their twenties who were estranged throughout their childhood, and are finally developing a close relationship. The series is set in San Francisco.

Half & Half was the second-most-watched show on UPN's Monday night line-up (next to Girlfriends) and fourth overall on the network. The series was almost renewed for a fifth season by The CW, but due to several circumstances—including the network's contractual obligation to pick up Reba, the last-minute renewal of All of Us, and the pick-up of the Girlfriends spin-off The Game—the series was left off the network's fall 2006 schedule and canceled. The series has aired in reruns on Global TV in Canada, Trouble in the United Kingdom and in local syndication, Bounce TV, TV One, Cleo TV, BET Her, and Dabl in the United States.

The series is available to stream on Netflix, Paramount+, and Amazon Prime Video.
