Maureen Denise McCormick (born August 5, 1956) is an American actress, celebrity and recording artist. She is most widely known as a child actress who played Marcia Brady in the television series The Brady Bunch from 1969 to 1974.
McCormick was born in Encino, California, the daughter of Irene (née Beckman) and William McCormick, a teacher. At the age of six she won the Baby Miss San Fernando Valley beauty pageant. McCormick first appeared on national U.S. television in 1964 for Mattel toys on Barbie and Chatty Cathy doll commercials. She lent her voice to a redesigned Chatty Cathy doll in 1970. Through the later 1960s McCormick appeared in two episodes of Bewitched and played guest roles on I Dream of Jeannie, Honey West, The Farmer's Daughter and My Three Sons. (She confesses she had a crush on Fred MacMurray at the time.)
McCormick played the eldest daughter, Marcia, who had five other siblings. She had a perky and popular personality in The Brady Bunch, an American television sitcom about a blended family that aired from late 1969 to early 1974 on ABC, Friday nights at 8pm. After its cancellation Brady Bunch episodes were rebroadcast in syndication for decades as children's programming, gathering a long lasting, cross-generational popularity that led to spinoffs and movies.
