Dumont is an unincorporated community in King County, Texas, United States.

Dumont was founded sometime in the late 1880s and named after the first postmaster of the nearby community of Paducah.

Though it has served as a minor center for shipping and commerce for several area ranches, the town has never been highly populated, reaching a high mark of 105 residents in 1960.

By 1980, this had fallen to 95, and in 1990 Dumont reportedly had three businesses in operation and a population of 85, a figure it maintained through to the 2000 Census.

[2] Dumont is served by the Guthrie Common School District.
