State Route 193 (SR 193) is part of Maine's system of numbered state highways.

It runs 19.08 miles (30.71 km) from an intersection at U.S. Route 1 (US 1) in Cherryfield to rural East Hancock, Hancock County at State Route 9 near Beddington.

The original route was renumbered SR 175, and 193 was moved to its current location.

The new route originally ran closer to Beddington Lake, but the road was not suitable for heavy traffic, and a new connector to its current terminus was built in 1956.
