The Caretakers (released in the UK as Borderlines) is a 1963 American drama film starring Robert Stack, Polly Bergen, Diane McBain, Joan Crawford and Janis Paige in a story about a mental hospital.

The screenplay was adapted by Henry F. Greenberg from a story by Hall Bartlett and Jerry Paris based on the 1959 novel The Caretakers by Dariel Telfer. The film was produced and directed by Bartlett, co-produced by Paris and distributed by United Artists. The Caretakers is reminiscent of The Snake Pit (1948), a film set in a similar hospital. The on-screen text in opening credits states: "Dedicated to the caretakers whose research and sacrifice discover truth. For Beba, Alice, Paul, Cathy, Laurie, Pearl, Margaret, Warren, Arthur".
