Diana Thorneycroft (born 1956 in Claresholm, Alberta) is a Canadian artist based in Winnipeg, Manitoba, known for her provocative photography, sculpture, and installation art. Her work explores themes of sexuality, national identity, and cultural icons, often using staged dioramas to challenge conventional narratives. Thorneycroft’s art blurs boundaries between gender and national identity, incorporating symbolism such as phalluses to explore complex social dynamics. She holds an MFA from the University of Wisconsin and a BFA from the University of Manitoba. With extensive exhibitions across Canada, the U.S., and Europe, her notable works include Canadians and Americans (best friends forever … it's complicated) and Group of Seven Awkward Moments. Thorneycroft has also taught at the University of Manitoba’s School of Art for 25 years. Her work is held in prominent collections such as the National Gallery of Canada and the Winnipeg Art Gallery. She has received several awards, including the Manitoba Arts Award of Distinction in 2016.
