The Queensway (or Queensway) is a major street in the municipalities of Toronto and Mississauga, Ontario, Canada. It is a western continuation of Queen Street, after it crosses Roncesvalles Avenue and King Street in Toronto. The Queensway is a divided roadway from Roncevalles westerly until 600 metres of the South Kingsway (accessed by ramps) with its centre median dedicated to streetcar service. The road continues undivided west from there to Etobicoke Creek as a four- or six-lane thoroughfare.
After crossing the creek, it enters Mississauga under Peel Region jurisdiction as Peel Regional Road 20, as far west as Mavis Road, with the westernmost portion to Glengarry Road being maintained by the city. There is a road allowance with hydro lines, cutting into the Mississaugua Golf & Country Club on the shores of the Credit River. In the 1990s, the name Queensway was eliminated on the roads on this allowance west of the river. The street gives its name to Etobicoke's the Queensway neighbourhood.
