Corpus Christi, city in southern Texas and a port of entry on Corpus Christi Bay, just southeast of the mouth of the Nueces River. It is the seat of Nueces County, though some parts of the city are in Kleberg and San Patricio counties. It has a landlocked harbor connected to the Gulf of Mexico by Aransas Pass, a break in the string of low sand islands stretching along much of the state's coast. Smaller vessels ply the Intracoastal Waterway between the islands and the mainland.
The city is a major shipping point and an important center of petroleum and natural-gas processing, the hub of a region with thousands of producing wells. Other manufactures include primary and fabricated metals, electronic equipment, and processed agricultural goods. Aircraft repair and maintenance and commercial fishing are also important industries. The city is the site of the large Corpus Christi Naval Air Station and a United States Army depot. The area is served by the Corpus Christi International Airport.
