Calallen's name comes from Calvin Joseph (Cal) Allen (1859–1922), a prominent early rancher. Allen owned a 4,000-acre (16 km2) cattle ranch on which the Calallen Independent School District is now located. Allen donated land to the St. Louis, Brownsville and Mexico Rail Line as right-of-way; in exchange, the railroad agreed to place a depot on Allen's property. Allen then subdivided the land adjacent to the depot and established a townsite there. The town was named Calvin until it was discovered that another community in Texas already had that name. Founded in 1910, Calallen was annexed by the city of Corpus Christi in 1970.[2]
