The Famous Five, also known as The Valiant Five, and initially as The Alberta Five, were five prominent Canadian suffragists who advocated for women and children: Henrietta Muir Edwards, Nellie McClung, Louise McKinney, Emily Murphy, and Irene Parlby. On August 27, 1927, they petitioned the federal government to refer the issue of the eligibility of women to be senator to the Supreme Court of Canada. This petition was the foundation of the Persons Case, a leading constitutional decision. Although most Canadian women had the vote in federal elections and all provinces but Quebec by 1927, the case was part of a larger drive for political equality. This was the first step towards equality for women in Canada and was the start to the first wave of feminism.

Henrietta Muir Edwards was a Canadian women's rights activist, author and reformer. She was the eldest of "The Famous Five", along with Emily Murphy, Nellie McClung, Louise McKinney and Irene Parlby, who fought to have women recognized as "persons" under the law, and for the woman's right to vote in elections.
