Lennox Grafton (born 1920) is a Canadian architect and one of the first women to be trained as architects in Canada. She completed her undergraduate education in University of Alberta during 1938-1941 and graduated from the architectural program in University of Toronto in 1950. Grafton's early works during the same decade focused on schools, churches, and commercial building. These works were complete while she worked in several of Toronto architectural firms. In 1960 she started her own architectural practice, but had to eventually shutter it due to the lack of available funding to scale the business to acquire larger projects.
