Abby is an American sitcom created by Nat Bernstein and Mitchel Katlin that aired for one season on UPN from January 6, 2003, to March 4, 2003. The show revolves around television producer Abigail "Abby" Walker (Sydney Tamiia Poitier) and her relationship with her ex-boyfriend Will Jeffries (Kadeem Hardison). After they break up in the pilot episode, they agree to live together as friends in their rent-controlled San Francisco apartment.

Bernstein and Katlin had intended to feature Abby and Will as an interracial couple and had cast Sean O'Bryan, a white actor, as Will. After a negative response from test audiences, they gave the role to Hardison and recast O'Bryan as a supporting character, along with Randy J. Goodwin and Tangie Ambrose.

Critics classified Abby as a sex comedy and romantic comedy. Despite UPN's heavy promotion, it attracted a weekly average of 1.7 million viewers, making it the lowest-performing show tracked by Nielsen Holdings. Critical responses were primarily negative; commentators praised Poitier's acting but criticized the show's reliance on sexual humor.
