Cheryl Hardcastle is a Canadian politician and former member of Parliament in the House of Commons of Canada for the federal electoral district of Windsor—Tecumseh, first elected during the 2015 Canadian federal election. She is a member of the New Democratic Party. During the 42nd Canadian Parliament, NDP Leader Thomas Mulcair appointed Hardcastle to be the party's critic for Sports and Persons with Disabilities. After Mulcair was replaced Jagmeet Singh, he added "International Human Rights" to her critic duties, where she now sits as Vice-Chair to the Subcommittee for International Human Rights. She lost her re-election bid in the 2019 Canadian federal election, having come second in what was considered a surprise upset to the Liberal candidate Irek Kusmierczyk.
