Sheila Butler RCA (born 1938) is an American-Canadian visual artist, educator, and advocate known for her explorations of the human condition and the treatment of women. A founding member of Mentoring Artists for Women's Art (MAWA) in Winnipeg and the Sanavik Inuit Cooperative in Baker Lake, she has significantly contributed to the development of Canadian art communities. Educated at Carnegie Mellon University, Butler moved to Canada in 1962 and worked extensively with Inuit artists in the Northwest Territories, fostering printmaking and craft initiatives. She later became a professor at the University of Manitoba, University of Winnipeg, and University of Western Ontario, influencing generations of artists until her retirement in 2004. Her work—ranging from delicate drawings to bold paintings—addresses themes of violence, fear, and social issues, often inspired by media imagery. Acclaimed yet underrecognized, her art has been exhibited internationally, including in the National Gallery of Canada, the Winnipeg Art Gallery, and the Art Gallery of Hamilton.
