Alexis Colby (maiden name Morell; formerly Carrington; later Dexter and Rowan) is a fictional character on the American TV series Dynasty. She is the ex-wife of Blake Carrington (John Forsythe) whose schemes cause one problem after another for him and their children. The role was originated by Joan Collins in the first episode of the show's second season in 1981 (the character appeared briefly in the first season finale, non-speaking and face unseen). Collins remained on the show until the finale in 1989, and then returned as Alexis for the 1991 miniseries Dynasty: The Reunion.
