蒙哥马利·克利夫特（Montgomery Clift，1920年10月17日－1966年7月23日），美国演员，出生于内布拉斯加州奥马哈。

克利夫特在他的职业生涯中获得4个奥斯卡奖提名，包含最佳男主角和最佳男配角。1956年因车祸毁容后，他滥用酒精和处方药，变得飘忽不定。

克利夫特的首次荧幕处女作是1948年和约翰·韦恩一起合作的电影《红河谷》，并一炮而红。个人生活方面，直到1950年代早期，克利夫特是同性恋者,虽然他继续隐藏他的性取向并和多位女影星保持着非常暧昧的友情，尤其是和伊丽莎白·泰勒的关系。

Edward Montgomery "Monty" Clift (October 17, 1920 –July 23, 1966) was an American film and stage actor. The New York Times’ obituary of Clift noted his portrayal of "moody, sensitive young men". He often played outsiders and "victim-heroes", such as the social climber in George Stevens's A Place in the Sun, the anguished Catholic priest in Alfred Hitchcock's I Confess, the doomed soldier in Fred Zinnemann's From Here to Eternity, and the would-be deserted soldier in Edward Dmytryk's The Young Lions. Clift received four Academy Award nominations during his career, three for Best Actor and one for Best Supporting Actor.
