The Thunder Bay Expressway, originally known as the Lakehead Expressway is a high-capacity at-grade suburban limited access highway corridor around the western side of Thunder Bay in the Canadian province of Ontario. The 15.3 km (9.5 mi) route travels in a generally north–south direction on the city's west side. It carries a part of Highway 61 at its southern segment, and a part of the concurrent routes Highway 11 and Highway 17 at the six remaining segments. The expressway features several at-grade intersections between its southern terminus at Arthur Street West and its northeastern terminus at Hodder Avenue.

The Thunder Bay Expressway was built throughout the mid-to-late 1960s, and opened in stages between mid-1967 and late 1970, rerouting Highway 11/17 around the city. The old routes of Highway 11/17 and Highway 61 through Thunder Bay were redesignated as Highway 11B/17B and Highway 61B. In 2008, following the opening of the “Shabaqua Highway” segment of the 11/17, the segment between Arthur Street and Harbour Expressway was transferred to Highway 61. Work is now ongoing to twin Highway 11/17 northeast to Nipigon.
