Washburn is an unincorporated community and census designated place (CDP) in Armstrong County, Texas, United States.

Robert E. Montgomery, who owned section 98, established this townsite at the ending point of the Fort Worth and Denver Railway in August of that same year.

Two water wells, a double pump station, a coal chute, a section house, a depot, and stock pens were all established in the community along the Denver Road.

Washburn grew to have tents, dugouts, and board shacks and was a base of operations for settlers, ranchers, and other nearby communities.

A post office was established at Washburn in March 1888 and remained in operation until 1956, with James Logue as postmaster, as well as justice of the peace in the community.

A community center was built in Washburn to modernize school campuses, improve education, and sponsor cultural events around 1920.
