Merle "Mimsy" Farmer is a former American actress, artist and sculptor. She began her career appearing in several Hollywood studio films, such as Spencer's Mountain (1963) and Bus Riley's Back in Town (1965), followed by roles in the exploitation films Devil's Angels and Riot on Sunset Strip.

Spencer's Mountain is a 1963 American family drama film written, directed and produced by Delmer Daves from the 1961 novel of the same name by Earl Hamner Jr. and starring Henry Fonda and Maureen O'Hara. The supporting cast features early appearances by James MacArthur, Veronica Cartwright and Victor French, while longtime Hollywood actor Donald Crisp portrays "Grandpa" in his final screen role. Wally Cox, Virginia Gregg, Lillian Bronson, Whit Bissell and Dub Taylor also appear. The movie, although set in Wyoming rather than the Blue Ridge Mountains of Virginia, is a forerunner of the television series The Waltons.
