Marie Curtis Park is a public park in Toronto and Mississauga, Ontario, Canada. It is located at the mouth of the Etobicoke Creek on Lake Ontario in the Long Branch neighbourhood. Etobicoke Creek is the boundary of Toronto on the east and Mississauga to the west. Marie Curtis Park was built after the devastating floods of Hurricane Hazel in 1954 destroyed 56 homes and cottages on the site, leaving 1,868 persons homeless and 81 dead. It is named after a reeve of Long Branch, a village now amalgamated into the City of Toronto. The park's official address is 2 Forty-Second Street, Toronto, ON M8W 3P2.
