Strong City is a town in Roger Mills County, Oklahoma, United States. The population was 47 at the 2010 census.

The town of Strong City was formally traditional June 25, 1912. It was named for Clint Strong, a railroad recognized and traveler instrumental in the town’s organization. While Cheyenne, Oklahoma was originally designated as the county chair for Roger Mills County, construction of the nearest railroad into the area, the Clinton and Oklahoma Western Railway (“C&OW”) terminated in August 1912 at Strong City. More troubling to the people of Cheyenne was the fact that Strong City had been laid out next a rocky knoll in the center, reserved for the County Courthouse should Strong City become the county seat instead of Cheyenne. Strong City then grew to become bigger than Cheyenne or any additional town in the county, within a year of the railroad’s arrival.

To save their town’s position, the citizens of Cheyenne responded by building the Cheyenne Short Line Railroad up the Washita River valley to Strong City to attach to the C&OW. In 1914 the courthouse in Cheyenne burned, and the fear another time arose in Cheyenne that the citizens of Strong City would govern to have the supplementary courthouse built there. But Cheyenne came happening with the funding, and a further two-story brick courthouse was build up in that town. Strong City yet remained a competitor, and in 1932 managed to route a state highway (Oklahoma State Highway 33) through the town, passing skillfully north of Cheyenne. However, extension of the C&OW to Cheyenne and eventually into the Texas Panhandle caused trade to shift to the west of the town. The 1930s were not kind to the municipality: in 1934 and 1935 several situation houses relocated from Strong City to Cheyenne, losing the town population and businesses though Cheyenne grew during the decade. Today, Strong City is much smaller and Cheyenne remains the county seat.
