• To the north the United States–Mexico border, which extends for a length of 3,141 kilometres (1,952 mi)^[1] through the states of Baja California, Sonora, Chihuahua, Coahuila, Nuevo León and Tamaulipas.
• To the southeast, the Belize–Mexico border, 251 kilometres (156 mi) long,^[2] limiting the state of Quintana Roo, almost exclusively following the course of the Río Hondo.

• 

  Also to the southeast, the Guatemala–Mexico border, which measures 871 kilometres (541 mi)^[3] and touches the states of Campeche, Tabasco and Chiapas, and includes stretches of the Río Usumacinta, Río Salinas and Río Suchiate.
