Guymon is the county seat of Texas County and the largest city in the Oklahoma Panhandle, sitting on the High Plains at an elevation of about 3,124 feet.

The town began when land promoter Edward T. E.T. Guymon bought a section of land west of the Beaver River in the 1890s, and it boomed after the Chicago, Rock Island and Pacific Railway arrived in 1901.

First named Sanford by the Post Office Department, the town was renamed Guymon a month later to avoid confusion with Stratford, Texas, and it incorporated in 1901.

When Oklahoma became a state in 1907, Guymon, with 839 residents, was named seat of the newly created Texas County, today the second-largest county in Oklahoma by land area.

Discovery of the nearby Hugoton-Panhandle gas field, one of the largest natural gas fields in the world, created new jobs and pushed Guymon's population to 2,290 by 1940.
