State Route 4 (abbreviated SR 4) is a 168.85-mile (271.74 km) long state highway located in southwestern Maine. Its southern terminus is at the New Hampshire border in South Berwick, where it connects to New Hampshire Route 4. Its northern terminus is at Haines Landing on Mooselookmeguntic Lake in Rangeley.
Major cities and towns along the length of SR 4 include Sanford, Gorham, Windham, Auburn and Farmington.
Approximately one-third of the overall length of SR 4 is overlapped by U.S. Route 202 (US 202).
