Jefferson Avenue is a major, seven lane wide, north to south thoroughfare in the city of St. Louis, Missouri. For much of its run in south city Jefferson Avenue and Grand Boulevard take a parallel course, separated by about sixteen blocks. In the northern city, their concurrence varies some.

Jefferson Avenue does not connect to the Metrolink light rail service, but MetroBus route 11 (Chippewa) does travel along much of the route.
