Lockhart State Park, State park in Caldwell County, United States.

Lockhart State Park covers 453 acres at the southwestern edge of Lockhart, in Caldwell County. Clear Fork Creek runs through its middle, crossed by a stone arch bridge and held back by small stone check dams built for fishing. Civilian Conservation Corps Company 3803 built the recreation hall, residence building, trailhead steps and picnic tables in a style recalling early Texas frontier homesteads.

The park was built in the 1930s by the Civilian Conservation Corps, which constructed stone buildings and water control structures. This work was part of a broader employment program during the Great Depression.

Informational panels in the park recount the Battle of Plum Creek, fought a few miles north in 1840 after Penateka Comanche chief Buffalo Hump led raids from the Guadalupe River to Matagorda Bay. Texas militia, Rangers and Tonkawa allies caught the Comanche near present-day Lockhart; the fighting was a running gunfight, and it was the last large-scale Comanche raid beyond the Texas frontier.

The park has fishing spots along Clear Fork Creek where anglers can fish without a special license and borrow equipment on site. The camping areas and trails are generally accessible during daylight hours and clearly marked throughout the grounds.

The nine-hole golf course was not built by the CCC but by the Works Progress Administration, completed by 1941, because the CCC's work was limited to conservation. The CCC only cleared the land for it.
