Lamanai is a Mesoamerican archaeological site, and was once a major city of the Maya civilization, located in the north of Belize, in Orange Walk District. The site's name is pre-Columbian, recorded by early Spanish missionaries, and documented over a millennium earlier in Maya inscriptions as Lam'an'ain. Lamanai is renowned for its exceptionally long occupation spanning three millennia, beginning in the Early Preclassic Maya period and continuing through the Spanish and British Colonial periods, into the 20th century. Unlike most Classic-period sites in the southern Maya lowlands, Lamanai was not abandoned at the end of the 10th century AD.

Mesoamerica is a historical region and cultural area that begins in the southern part of North America and extends to the Pacific coast of Central America, thus comprising the lands of central and southern Mexico, all of Belize, Guatemala, El Salvador, and small parts of Honduras, Nicaragua and Costa Rica. As a cultural area, Mesoamerica is defined by a mosaic of cultural traits developed and shared by its indigenous cultures.
