Margaret Anne Mitchell OBC (née Learoyd; July 17, 1925 – March 8, 2017) was a Canadian social activist and the New Democratic Party (NDP) Member of Parliament (MP) for Vancouver East from 1979 until 1993.

She is best remembered for one incident in which male MPs laughed when she demanded that the government take action to stop domestic violence.

From 1952 to 1955, she worked as a social worker for the International Red Cross in Japan, Korea, Australia and Austria.

In Parliament, she was variously the NDP's Critic for Immigration, Housing, Status of Women, Health and Welfare and for Multiculturalism and Citizenship.

[4] Mitchell was a known descendant[citation needed] of former Canadian Prime Minister Sir John Thompson who died in office in 1894 while visiting Queen Victoria at Windsor Castle.
