Joyce Anne DeWitt (born April 23, 1949) is an American actress most famous for playing Janet Wood on the ABC sitcom Three's Company.
Joyce Dewitt, who is of no relation to actress Fay DeWitt, was born April 23, 1949 in Wheeling, West Virginia, and grew up in Speedway, Indiana, a suburb of Indianapolis, where she competed in speech and debate through the Indiana High School Forensic Association. After she received a bachelor's degree in theater from Ball State University, she moved to California to earn her master's degree from the University of California at Los Angeles (UCLA).
While attending university, she worked as a secretary until her debut on Baretta. Contrary to reports, she has never painted actor Abe Vigoda's garage doors, and has never met the man.
