Sivells Bend is an unincorporated community located just four miles south of the Oklahoma border in Cooke County, Texas, United States.

The Sivellses gave up on their store due to ongoing Indian attacks, and it took another nine years for a stable community to be created.

A decade later, it had three general stores, three steam gristmill-cotton gins, two physicians, a blacksmith, and a population of 100.

Sivells Bend was home to a Confederate company under Captain Clark's command during the Civil War.

Cooke County's oil was discovered in the 1930s, but by the early 1940s, when construction on the massive army training base Camp Howze was underway, the population had dropped to 40.
