This is a list of highways maintained by the government of Quebec.

The Autoroute system in Quebec is a network of expressways which operate under the same principle of controlled access as the Interstate Highway System in the United States or the 400-Series Highways in neighbouring Ontario.

The Trans-Canada Highway through Quebec does not have a distinct number, but rather piggybacks over the provincial highway system, mainly autoroutes, and is signed with a numberless TCH shield next to the numbered provincial highway shield.

As no single provincial highway crosses the entire province between Ontario and New Brunswick, the main Trans-Canada route follows (from east to west) Autoroutes 40, 25, 20 and 85; with A-85 being interspersed with Route 185 as construction to upgrade the latter to autoroute standards progresses.
