Michelle Elizabeth Tanner is a fictional character on the long-running ABC sitcom Full House, who was portrayed by Mary-Kate and Ashley Olsen. She first appeared in the show's 1987 pilot, "Our Very First Show", and continued to appear up to the two-part series finale, "Michelle Rides Again", in 1995. The character of Michelle was the Olsen twins' first acting role; the two were nine months old when they started working on the series. Shortly after Full House ended, the sisters appeared in many films and TV shows up until their teenage years. Michelle Tanner does not appear in the 2016 Netflix sequel, Fuller House, as both Olsen twins declined to reprise the role.
