A map of San José Island.
San Jose Island or San José Island (also known as Saint Joseph Island) is a barrier island on the Gulf Coast of Texas in the United States. The island is about 21 miles (34 km) long and 5 miles (8 km) wide. The island is oriented generally northeast-southwest, with the Gulf of Mexico on the east and south, Aransas Bay on the west, and Mesquite Bay on the north. At the southern end of the island is Aransas Pass (not to be confused with the City of Aransas Pass which is on the mainland), beyond which is Mustang Island and the town of Port Aransas. Aransas Pass is protected by jetties extending into the Gulf from both Mustang Island and San José Island. The island’s northern end used to be separated from Matagorda Island by Cedar Bayou. Cedar Bayou does not run freely through the two islands any longer.

On July 26, 1845, Lt. Chandler of the USS Alabama waded ashore and planted the first American flag to fly over Texas territory on a sand dune on San Jose Island. Units of the Third Infantry established a small military town known as Aransas. A stagecoach service brought passengers, goods and mail to the town, and a ferry connected the island with the mainland. During the American Civil War, the Union Army removed livestock from the island and assaulted the town of Aransas, of which no obvious trace today remains. After the war, the island’s sole town ceased to exist, and it became an exclusive hunting and fishing resort.
It was purchased by Texas oilman Sid W. Richardson and used as his private island. On it he built a lavish hunting lodge at great expense, to which prominent businessmen and politicians, including then Senator Lyndon B. Johnson and President Franklin D. Roosevelt, were invited.
Buried on St. Joseph Island across from Rockport are ornaments and gold that were designed for a Vera Cruz cathedral.
Another treasure on St. Joseph Island near the southern end is payroll that was intended for Spanish soldiers.
