State Highway 47 (SH-47 or OK-47) is a state highway in Oklahoma. It runs 94.6 miles (152.2 km) west-to-east in Roger Mills, Dewey and Custer counties.
The current SH-47 was first established in late 1936. Over time it was expanded, reaching its current extent in 1945. A lettered spur route, SH-47A, was added in 1965.
State Highway 47 begins at the Texas state line, where FM 2124 becomes SH-47 upon entering Oklahoma, in the Black Kettle National Grassland. Four miles (6.4 km) later, SH-30 joins the highway for a three-mile (5 km) concurrency just south of Reydon. Just outside the community of Rankin, SH-30 turns to the south, and SH-47 continues off to the east.
A few miles west of Cheyenne, SH-47A branches off in a loop to the north, rejoining Highway 47 in a couple of miles. South of Cheyenne, SH-47 joins US-283 for a concurrency to the north. SH-33 also joins in on the concurrency, with a signed direction opposite that of SH-47 (a wrong-way concurrency). SH-47 and US-283/SH-33 parts ways at Roll, where SH-47 resumes its travel to the east.
