Galveston Island State Park, State park on Galveston Island, Galveston County, Texas, United States.

Galveston Island State Park is a 2,013.1-acre Texas state park on the western end of Galveston Island, in Galveston County, Texas, United States. It protects surf, beach, dunes, coastal prairie, fresh-water ponds, wetlands, bayous and bay shoreline. A wooden boardwalk bridge with plank decking and railings crosses flat ground above the water, and a low hill of dry grass, shrubs, a dead leafless tree and a cluster of fan palms rises beyond a calm body of water.

Maco Stewart Jr., whose father founded Stewart Title Company, owned over 2,000 acres on Galveston Island and directed in his will that his "Galveston Island home" pass to the state of Texas as a fish, game, and oyster preserve. In 1969, under the State Parks Bond Program, 1,950 acres were bought from his heirs, and the park opened in 1975. Tropical Storm Frances destroyed its dunes in 1998; recycled Christmas trees were used to trap sand and rebuild them. Hurricane Ike closed the park in 2008, and it reopened for outdoor recreation and camping in July 2009.

The park teaches visitors about the delicate balance of coastal ecosystems through signage and guided walks that highlight local plants and animals. These learning opportunities help people understand how human activity affects this natural environment.

The main entrance is on FM 3005 with separate access points for the beach and bay sides, and parking is available at both locations. Wear appropriate shoes as trails cross sandy areas and uneven terrain.
