La Blanca is a Maya pre-Columbian Mesoamerican archaeological site in the municipality of Melchor de Mencos in the northern Petén Department of Guatemala. It has an occupation dating predominantly from the Middle Preclassic (900–600 BC) period of Mesoamerican chronology. This site belongs to the later period of the Mokaya culture. The site is located in the lower reaches of the Mopan River valley and features a large acropolis complex. Activity at the site has been dated as far back as the Early Classic (AD 250–600), with principal occupation of the site occurring in the Late Classic period (AD 600–900), although some level of occupation continued into the Early Postclassic (AD 900–1200).
