Douglas Patrick Haig (March 9, 1920 – February 1, 2011) was an American child actor appearing in films in the 1920s and 1930s. His career began at age two in silent films and (unlike many silent film actors) continued into sound films ("talkies").

From 1928 onward he appeared in at least 14 films. As a small child he was placid and pleasant-looking. In a scholarly review of Attorney for the Defense, a 1932 sound film, his performance is described as very annoying.
