Francis Conroy Sullivan (July 2, 1882 – April 4, 1929) was a Canadian architect.

The only Canadian pupil of Frank Lloyd Wright aside from Roger d'Astous, Sullivan worked in the Oak Park studio in 1907 but returned to Ottawa in 1908. Sullivan brought the modernist Prairie School style to Canada, building a number of prominent structures, often in the Prairie Style.

Sullivan was born in Kingston, Ontario. He was an architect for the Canadian Department of Public Works from 1908 to 1911, after which he had an independent practice in Ottawa until 1916. In this capacity he frequently designed schools for the Ottawa Catholic School Board. In 1920 he moved to Chicago and became the chief architect for the Chicago Public School Board.

Although influenced by Wright, Sullivan's work diverged from Wright's in certain important ways. For example, whereas horizontals predominate in Wright's creations, Sullivan used strong verticals to create tension in his designs.

Sullivan went to Chandler, Arizona while in Wright's employ, and died there on April 4, 1929.^[6]
