ALF is an American television sitcom that aired on NBC from September 22, 1986, to March 24, 1990. The title character is ALF (an acronym for "alien life form").

ALF is an alien from the planet Melmac who follows an amateur radio signal to Earth and crash-lands into the garage of the Tanners, a suburban middle-class family who lives in the San Fernando Valley area of California. The family consists of social worker Willie (Max Wright), his wife Kate (Anne Schedeen), their teenage daughter Lynn (Andrea Elson), younger son Brian (Benji Gregory) and their pet cat Lucky (whom ALF wishes to consume).

Unsure what to do, the Tanners take ALF into their home and hide him from the Alien Task Force (a part of the U.S. military that specializes in aliens) and their nosy neighbors Trevor and Raquel Ochmonek (John La Motta and Liz Sheridan), until ALF can repair his spacecraft. He generally hides in the kitchen. It is eventually revealed that ALF's home planet Melmac exploded, due to nuclear war.
