Sweetwater is a town in Beckham and Roger Mills Counties in the U.S. state of Oklahoma.

The town did expand to about 100 people around the time of World War I, based on being an agricultural service center for the surrounding township, and the postmaster estimated 150 in the 1930s.

However, the population started a decline even before World War II, as improved roads and automobile transportation carried business south to Erick or east to Elk City.
