U.S. Route 202 (US 202) is a highway stretching from Delaware to Maine, also passing through the states of Pennsylvania, New Jersey, New York, Connecticut, Massachusetts, and New Hampshire. The road has borne the number 202 since at least 1936. Before this, sections of the road were designated U.S. Route 122, as it intersected U.S. Route 22. Its current designation is based on its intersection with US 2 in Maine.

This route is considerably longer than the eastern segment of US 2, making it one of several 3-digit US routes to be longer than their parent routes.

US 202 begins at an interchange with US 13/US 40 south of Wilmington. It runs north along the same road as Delaware Route 141, then joins with Interstate 95 through Wilmington. North of the city, it exits the freeway onto Concord Pike, heading north; Delaware Route 202 also continues south from this point. US 202 continues north towards the state line as a six-lane arterial road and is lined with numerous strip malls and "big-box stores".
