Lake Corpus Christi State Park, State park with lake access in San Patricio County, US.

Lake Corpus Christi State Park is a 356-acre Texas state park on Lake Corpus Christi in San Patricio County, southwest of Mathis. Its mix of brushland, wetland, woodland and open water supports honey mesquite, huisache and anacua. Civilian Conservation Corps Company 886 built the park in 1934–1935; of its bathhouse, park residence, boat house and refectory, only the refectory remains, alongside a lookout tower, Park Road 25 and bridges.

The park was built between 1934 and 1935 by the Civilian Conservation Corps as part of Depression-era work programs, with stone structures, bridges, and roads constructed in a Mediterranean style. Many of those original elements are still standing and give the park much of its current character.

The park's name comes from Lake Corpus Christi, the reservoir it borders in San Patricio County. The Civilian Conservation Corps left a refectory, a lookout tower, bridges and Park Road 25, built in 1934 and 1935; the refectory is the only CCC building still standing. Anglers come for blue, channel and yellow catfish, sunfish, bass and crappie.

The park has two lit fishing piers, one of which is wheelchair accessible, making it easy to reach the water from different points along the shore. Open lakeside areas can be very exposed to the sun, so bringing water and sun protection is a good idea year-round.

The park sits along a key route for birds traveling between North and South America, and over 200 species have been recorded here across different seasons. This makes it one of the more active spots for bird watching along the Texas Gulf Coast.
