Culleoka is a populated place in Collin County, Texas, United States.

The early settlers of Culleoka named the community for their hometown in Tennessee.

There was a post office at Culleoka from 1893 to 1906, catering to an estimated fifty residents.

The area had a downturn in the late 1940s, partly because of the expansion of Plano nearby and the disturbance brought about by the construction of Lavon Dam in 1954, which created a sizable reservoir.

[2] Culleoka is located on a spur off of Farm to Market Road 982 near Lavon Lake, 10 mi (16 km) east of McKinney in east-central Collin County.
