Tonina (or Toniná in Spanish orthography) is a pre-Columbian archaeological site and ruined city of the Maya civilization located in what is now the Mexican state of Chiapas, some 13 km (8.1 mi) east of the town of Ocosingo. Toniná was an aggressive state in the Late Classic, using warfare to develop a powerful kingdom. For much of its history, Toniná was engaged in sporadic warfare with Palenque, its greatest rival and one of the most important polities in the west of the Maya region, although Toniná eventually became the dominant city in the west.
