Hendrix is a town in Bryan County, Oklahoma, United States. The population was 79 at both the 2010 and the 2000 censuses.

Hendrix was named for the owner of a general store named James A. Hendrix. originally called Kemp City when the Missouri, Oklahoma and Gulf Railway (MO&G) bypassed the town of Kemp in 1908 while building a line to Texas. In 1910, residents petitioned the Oklahoma Corporation Commission to force the MO&G to build a side track and stop station called Kemp City at present-day Hendrix. The commission ordered the railroad to satisfy the request, but the MO&G appealed to the Oklahoma Supreme Court, which upheld the commission in 1911.
