Chinkultic, sometimes Chincultic, is a moderate-size archeological ruin in the state of Chiapas, Mexico, some 56 km from Comitán, the nearest city. It is part of the Lagunas de Montebello National Park.

This pre-Columbian city belongs to the ancient Maya civilization. The city flourished in the Maya Classic Era, from about the 3rd through the 9th century. Most of the sculptures were produced in the last 300 years of this era, with hieroglyphic inscriptions dating from 591 to 897. Post-Classic-Era occupation of the site continued until the 13th century, after which it was abandoned.

The site has some step-pyramids and some 200 smaller buildings, most in undisturbed ruin. Chinkultic has carved stone stelae depicting the site's rulers. The site contains a court for playing the Mesoamerican ballgame, which a marker tells us was dedicated on 21 May 591.

The first published account of the site was made by Edward Seler in the late 19th century. A detailed description of the site was made by Enrique Juan Palacios in 1926.
