Thomas Mower Martin RCA (1838–1934) was an English-born Canadian landscape painter, often called the "father of Canadian art." Originally trained as a carpenter and draughtsman, he emigrated to Canada in 1862, settling in Toronto after an unsuccessful attempt at farming in Muskoka. Largely self-taught, he became known for his landscapes, portraits, and etchings, working in oils and watercolours. A founding member of the Ontario Society of Artists (1872) and the Royal Canadian Academy of Arts (1880), he was also among the "Railway Painters" commissioned by the Canadian Pacific Railway to document the western frontier. His work is held in public and private collections, including Windsor Castle.
