Rita Letendre (1928–2021) was a Canadian painter, muralist, and printmaker associated with Les Automatistes and the Plasticiens. Born in Drummondville, Quebec, of Abenaki and Québécois descent, she studied at the École des beaux-arts de Montréal before embracing abstract art. Influenced by Paul-Émile Borduas, Letendre transitioned from figuration to abstraction, later incorporating geometric elements and hard-edge painting. She gained recognition for her dynamic compositions, large-scale murals, and use of airbrush techniques. Letendre received numerous accolades, including the Order of Canada (2005) and the Governor General’s Award (2010). Her work remains a significant contribution to Canadian modern art.
