Louise McKinney (née Crummy; 22 September 1868 – 10 July 1931) was a Canadian politician, temperance advocate, and women's rights activist.

McKinney was heavily involved in the Methodist Church[1] and the Woman's Christian Temperance Union, and she served as president of the Alberta branch for 22 years, from 1908 to 1930.

[6] She was elected as the North Dakota WCTU's District President in 1898 and represented her area at the National Convention the following year.

[2] The McKinneys continued to farm in North Dakota until 1903, when they moved to the Northwest Territories (present-day Alberta) and settled near Claresholm.

Together with Henrietta Muir Edwards, she drafted and introduced a motion which ensured widows would receive a portion of their husbands' estate.

[10] Several of her fellow Famous Five members, including Parlby, Murphy, and McClung, were supporters of the eugenics movement in Alberta.

[14][15] McKinney was one of the Famous Five, along with Irene Parlby, Henrietta Muir Edwards, Emily Murphy and Nellie McClung, a group of five women who fought for the right to be considered "persons" and be eligible to serve in the Senate of Canada.

In 1929, the Five appealed the ruling at the Judicial Committee of the Privy Council, Canada's highest court at the time.

[17] The Judicial Committee overturned the Supreme Court's decision, and the first woman, Cairine Wilson, was appointed to the Senate the following year.

[18] McKinney fell ill during the WCTU World Convention in June 1931, and her sickness became worse after her return to Claresholm.

[22] In 2000, two identical monuments were created in Calgary, Alberta, and near the Senate of Canada Building, in Ottawa, Ontario.
