Utah State Route 63 (SR-63) is a state highway in the U.S. state of Utah. Just 2.63 miles (4.23 km) long, it serves as a connection between Utah State Route 12 (a scenic byway) and Bryce Canyon National Park.

Starting from the northern edge of Bryce Canyon National Park, the route runs northward, passing a view area, and exiting Dixie National Forest within the first mile. It continues north until its terminus at the intersection with SR-12 less than two miles later.

This route number was originally in use from 1931 – 1971 as a route from Salina to Scipio. The route number was withdrawn when this route was transferred to SR-26, and subsequently designated as part of US-50.

Utah State Route 12 originally had a short spur serving Bryce Canyon. This spur was split off into a distinct highway, SR-63, in 1975.

The entire route is in Garfield County.
