Tuxtla Gutiérrez, or Tuxtla, is the capital and the largest city of the Mexican southeastern state of Chiapas. It is the seat of the municipality of the same name, which the most developed and populous in the state. A busy government, commercial and services-oriented city, Tuxtla had one of the fastest-growing rates in Mexico over the last 40 years.

Metropolitan areas of Mexico have been traditionally defined as the group of municipalities that heavily interact with each other, usually around a core city, in Mexico. The phenomenon of metropolization in Mexico is relatively recent, starting in the 1940s. Because of an accelerated level of urbanization in the country, the definition of a metropolitan area is reviewed periodically by the Mexican population and census authorities.
