McAllen, city, Hidalgo county, southern Texas, U.S., in the irrigated lower Rio Grande valley, 7 miles (11 km) from the International Bridge to Reynosa, Mexico, and some 50 miles (80 km) west-northwest of Brownsville. With Edinburg and Pharr, McAllen forms a metropolitan complex. Founded in 1905, it was named for John McAllen, a Scottish settler whose ranch was the town site. The city has long had a large population of Mexican descent; segregation and a transformation from a ranching economy (Mexican dominated) to a farming economy (dominated by white settlers) raised tensions in the city. A leading winter resort, McAllen is a hub of oil and gas production. It is also a processing centre for citrus fruits, vegetables, and cotton, and it is one of the most important ports of entry for trade with Mexico. The city’s foreign trade zone flourished in the 1980s. The International Museum of Art and Science and the Hidalgo County Historical Museum are located in McAllen. Popular local events include the Texas Square Dance Jamboree, held annually in February, and Borderfest (March), which celebrates the city’s Mexican-American heritage. Inc. town, 1910; city, 1927.
