Garner State Park is a state park in the community of Concan, in Uvalde County, Texas, United States. The park is on the Frio River.

In the early 1930s the park was built to save a portion of the hill country for the public, and to provide work for unemployed men during the economic depression. The land for Garner State Park was acquired in 1934 through 1936. In 1934, the Texas State Parks Board approved the location for a future state park, and the Texas Legislature provided funding for state parks. The Civilian Conservation Corps built the park’s original improvements, which included a large pavilion and a concessions building. The property was conveyed to the State Parks Board in 1936, and it opened as Garner State Park in 1941. The park was named for John Nance Garner, former Vice-President of the United States who lived and practiced law in the Concan area. The park's size more than doubled when 790 acres (320 ha) were added in 1976.
