Fort Crockett is a government reservation on Galveston Island overlooking the Gulf of Mexico originally built as a defense installation to protect the city and harbor of Galveston and to secure the entrance to Galveston Bay, thus protecting the commercial and industrial ports of Galveston and Houston and the extensive oil refineries in the bay area. The facility is now managed by the US NOAA National Marine Fisheries Service, and hosts the Bureau of Commercial Fisheries Laboratory, the Texas Institute of Oceanography, as well as some university facilities. The area still contains several historical buildings and military fortifications.

Galveston is a coastal resort city and port off the Southeast Texas coast on Galveston Island and Pelican Island in the U.S. state of Texas.

It is also within the Houston–The Woodlands–Sugar Land metropolitan area at its southern end on the northwestern coast of the Gulf of Mexico.
