Aransas County is a small coastal county in south Texas. Over half if its total area is water. Its county seat is Rockport. It is in the Corpus Christi metropolitan area. It was named after the Aransas River. "Aransas" is an anglicized form of the Spanish aránzazu, which is a reference to a Basque legend called "The Lady of Aranzazu." Aransas County was created in 1871 wholly out of Refugio County after the fallout from the Texas legislature's decision earlier that year to move the county seat from Refugio to Rockport.
