Bolivar (/ˈbɒlɪvər/ BOL-i-vər) is an unincorporated community in northern Denton County, Texas, United States.

William Crawford gave the land to Methodist physician and clergyman Hiram Daily, who established a general store and planned the town.

John Simpson Chisum lived close to Bolivar, but in 1863 he relocated his herds to West Texas.

Merchants from Bolivar relocated to Sanger that year, along the Gulf, Colorado and Santa Fe Railway.

The thriving town boasted multiple establishments such as a sawmill, gin, flour mill, bar, blacksmith shop, church, and school.
