Walter William LaChance (1870–1951) was a Canadian architect best known for his designs of rural schools, although he also designed numerous buildings of other types. His commissions were concentrated in Cleveland, Ohio, Hamilton, Ontario, Welland, Ontario, and various communities in Saskatchewan. While his practice was varied in terms of building type, he designed at least 16 schools for various Saskatchewan communities from 1906 to 1914. He was also the author of two books, Modern Schoolhouses (Toronto, 1919) and Schoolhouses and Their Equipment (Niagara Falls, New York, 1925).
