Jeffrey Charles William Michael Conaway was an American actor, best known for his roles in the movie Grease, and the US TV series Taxi and Babylon 5. He also directed the 1992 film Bikini Summer 2.

Jeff spent some of his time living with his grandparents in South Carolina, which gave him enough of a Southern accent that when he accompanied his mother to a casting call for director Arthur Penn's Broadway play All the Way Home, a story set in Knoxville, Tennessee, the 10-year-old Conaway landed a featured role as one of four boys. The 1961 Pulitzer Prize-winning play was nominated for a Tony Award for Best Play and ran 333 performances and one preview from November 29, 1960, to September 16, 1961.Conaway remained for the entire run, then toured with the national company of the play Critic's Choice.
