The Gran Basamento ("Great Platform") is the largest structure at Chacchoben in southern Quintana Roo, Mexico, an elevated ceremonial precinct supporting three temple pyramids on a single massive limestone platform. The complex was built primarily between 200 and 700 CE during the Late Preclassic and Early Classic, with later modifications continuing into the Postclassic. The platform itself rises 8 metres above the plaza floor and covers roughly 5,000 square metres, with the largest summit pyramid adding another 12 metres of elevation. Chacchoben was a regional centre serving the inland Maya population of the southern Yucatán, with continuous occupation from at least 200 BCE through 1000 CE. The site was first documented by Peter Harrison in 1972 and systematically excavated by Juan Esteban Cocom Bolio and INAH teams beginning in 1994.

The Gran Basamento is a stone platform big enough to hold a small village, holding three temples instead.
