Oakville is an unincorporated community in northeastern Live Oak County, Texas, United States.

Originally referred to by the name of the local Sulphur Creek, it received its current name from an advertisement in a newspaper.

After the Civil War, Oakville became a local commercial center; the county's first bank and public school were established there, and the Live Oak County Leader, a newspaper, was founded in the community in 1891.

In December 1914, a group of local Mexicans came to the rescue of two compatriots, Ysidro González and Francisco Sánchez, when they were unjustly apprehended by the local law enforcement agency and a group of whites threatened to lynch them, a common occurrence at the time without due process.

Harry Hinton, the Oakville jailer, was murdered as a result of the jail breakout.
