St. Andrew—St. Patrick was a provincial electoral district in Ontario, Canada, that returned Members of Provincial Parliament (MPPs) to the Legislative Assembly of Ontario at Queen's Park. The riding was created before the 1967 election when the former electoral districts of St. Andrew and St. Patrick were merged. The riding was located in downtown Toronto between Yonge Street to Bathurst Street and included areas such as Spadina Avenue, Kensington Market, the Annex and the affluent neighbourhood of Forest Hill.
