约翰·巴里摩（英语：John Barrymore，1882年2月15日－1942年5月29日）是美国20世纪初期演员，是美国无声电影最初实验作品《唐璜》的主角。

John Barrymore (born John Sidney Blyth; February 14 or 15, 1882 – May 29, 1942) was an American actor on stage, screen and radio. A member of the Drew and Barrymore theatrical families, he initially tried to avoid the stage, and briefly attempted a career as an artist, but appeared on stage together with his father Maurice in 1900, and then his sister Ethel the following year. He began his career in 1903 and first gained attention as a stage actor in light comedy, then high drama, culminating in productions of Justice (1916), Richard III (1920) and Hamlet (1922); his portrayal of Hamlet led to him being called the "greatest living American tragedian".
