Garfield Boulevard is an east-west street on the south side of Chicago and its immediate western suburbs.

Its western segment, entirely known as 55th Street, runs east from Maple Avenue in Downers Grove until it becomes Joliet Road in Countryside.

In Clarendon Hills, the street intersects Illinois Route 83 (Kingery Highway).

The two segments of 55th Street are split because Interstate 55 (Stevenson Expressway) runs in its path if it were to continue in either direction.

About three-fourths of a mile further east, Garfield Boulevard intersects Interstate 90/Interstate 94 (Dan Ryan Expressway).

At Elsworth Drive in Washington Park, Garfield Boulevard is redesignated as 55th Street, intersecting Cottage Grove Avenue shortly east of this point.
