Reynosa

Reynosa is the largest city in the Mexican state of Tamaulipas and the municipal seat of Reynosa Municipality. It sits on the southern bank of the Rio Grande, directly across the border from Hidalgo, Texas, and forms part of the international Reynosa-McAllen metropolitan area, which has about 1,500,000 inhabitants and is the third largest metropolitan area on the Mexico-United States border after San Diego-Tijuana and El Paso-Juárez. The city has a recorded population of 691,557 as of 2025, and the total can reach about 1,000,000 if the floating population is counted. It was founded on 14 March 1749 as the Villa de Nuestra Señora de Guadalupe de Reynosa during the Escandón colonization of the region, was moved to its present site in 1802 after floods, and became a city on 24 November 1926. Today several satellite companies of United States firms operate there to take advantage of low labor costs and industry incentives.
