María Martínez-Cañas (born 1960) is a Cuban-born photographer whose work primarily deals with her Cuban heritage and journeys of discovery.
She received a Fulbright-Hays Fellowship in 1985 to photograph and do research in Spain, relating to the discovery of Cuba by Christopher Columbus.
During this visit she began combining her graphic designs with maps, initially with those that Christopher Columbus sketched on his voyages to the New World.
Documents related to Cuba often have formed the basis for Martínez-Cañas's photographs and are sometimes contrasted with door and windows that suggest openings and closings; the revealed and the hidden.
Some of her later work has been creating photograms by placing vegetative matter from her backyard between photographic paper and a light source.
