Michelle D. Douglas (born December 30, 1963) is a Canadian human rights activist who launched a landmark legal challenge in the Federal Court of Canada against the military's discriminatory policies against LGBTQ+ service members.

[1][3] During her trial, Douglas reported that while under investigation, she was taken to a hotel room where two male officers questioned her about her sexual activities and forced her to like men.

[5] Douglas subsequently launched a $550,000 lawsuit against the Department of National Defence in January 1990 where she was represented by Clayton Ruby.

[5] In October 1992, just before Douglas' legal challenge went to trial, the Canadian military abandoned its policy banning gays and lesbians and settled the case.

Douglas has supported other landmark rulings by participating as an intervener in the M v H and Vriend v Alberta cases in the Supreme Court of Canada.

[12] On December 13, 2023, the Minister of National Defence, The Honourable Bill Blair appointed Douglas as the first Honorary Colonel for Professional Conduct and Culture.
