Louise Allbritton (July 3, 1920 - February 16, 1979) was an American actress born in Oklahoma City, Oklahoma. She played in such films as Pittsburgh (1942), Son of Dracula (1943), The Egg and I (1947), and Sitting Pretty (1948).

Allbritton was the daughter of E.E. Allbritton of Wichita Falls, Texas. She attended the University of Oklahoma and gained acting experience in the Pasadena Playhouse. Her father cut off her allowance in hopes that she would return home, but her contract with Universal Studios enabled her to continue in Hollywood.

During World War II, Allbritton performed overseas with a USO troupe, a group that "[g]ave show after show, many of them to the accompaniment of the thunder of enemy guns."

She had a leading role in the Broadway production of "The Seven Year Itch", and appeared in the NBC-TV series "Concerning Miss Marlowe".

She was married to CBS news correspondent and author Charles Collingwood from 1946 until her death and retired several years after their marriage.
