Etobicoke ⁱ/ɛˈtoʊbɨkoʊ/ (with a silent 'k') is a district and a former municipality located within the current city of Toronto, Ontario, Canada. Comprising the western section of the current city, it had an official population of 347,948 residents as of the Canada 2011 Census. While it only contains 13% of Toronto's population, it occupies about 20% of its total land area. It is bordered on the south by Lake Ontario, on the east by the Humber River, on the west by Etobicoke Creek, the city of Mississauga and Toronto Pearson International Airport (though a small portion of the airport extends into Etobicoke) and on the north by Steeles Avenue West.

Different groups of First Nations peoples used the land that is now Etobicoke at different times. As the Algonquins gradually moved west from the Atlantic to Lake Erie, it is almost certain that they would have occupied this land at some point. By the time they were mostly settled on the shores of Georgian Bay, The Huron-Wendat were the primary residents of the north shore of Lake Ontario and, somewhere in the 17th century, they were pushed out by the Haudenosaunee (Iroquois) people. After continued harassment from the south, a coalition of the Ojibway, Odawa and Potawatomi Algonquin nations, known as the Three Fires, gradually pushed the Haudenosaunee off this land and the Mississaugas settled there by 1695, fishing and growing crops more locally in the summer and hunting further afield in the winter.
