Angus MacInnis (September 2, 1884 – March 3, 1964) was a Canadian socialist politician and parliamentarian.

MacInnis retained his status as an MP through five subsequent elections until his retirement in 1957, but sat in three different ridings.

He was an outspoken advocate of civil liberties and spoke against the discrimination against Japanese Canadians that was widespread in British Columbia in the 1930s and 1940s, and was an early advocate of extending the right to vote to Japanese Canadians, a right that was not won until 1949.

which, while a call for humane treatment of Japanese-Canadians, acquiesced to the prevailing mood at the time that favoured "evacuating" Japanese Canadians from the Pacific coast of British Columbia for reasons of wartime security.
