State Highway 102 (abbreviated SH-102 or OK-102) is a north–south state highway in central Oklahoma. It runs for 52.9 miles (85.1 km) from Wanette, Oklahoma to Wellston, Oklahoma. It has no lettered spur routes. SH-102 traces its origins to a spur route from SH-39 to Wanette that was added to the highway system in 1955. This highway was gradually extended bit by bit before reaching its present extent in 1977.
