The Diquis culture was a pre-Columbian indigenous culture of Costa Rica that flourished from 700 AD to 1530 AD. The word "disquis" means "great waters" or "great river" in Boruca language. The Diquis formed part of the Greater Chiriqui culture that spanned from southern Costa Rica to western Panama.

The Diguis Spheres of Costa Rica is an assortment of over three hundred petrospheres located on the Diquís Delta and on Isla del Caño. The spheres range in size from a few centimetres (0.3-1 in) to over 2 metres (6.6 ft) in diameter and weigh up to 15 tons. Most are sculpted from gabbro, the coarse-grained equivalent of basalt. There are a dozen or so made from shell-rich limestone, and another dozen made from a sandstone. They appear to have been made by hammering natural boulders with other rocks, then polishing with sand. They are thought to have been placed in lines along the approach to the houses of chiefs, but their exact significance remains uncertain.

In June 2014, the Precolumbian Chiefdom Settlements with Stone Spheres of the Diquis was added to the UNESCO list of World Heritage Sites.
