The Mirador Basin is a hypothesized geological depression found in the remote rainforest of the northern department of Petén, Guatemala. Mirador Basin consists of two true basins, consisting of shallowly sloping terrain dominated by low-lying swamps called bajos; one draining into the San Pedro River and the other into the Candelaria River. The basin is surrounded by rugged karstic limestone hills on the east and south, forming a triangular geographical "trough" covering more than 2,169 km2 (837 sq mi). The geological formation of the landscape, as well as the significance of the formation, are the subject of some controversy in Northern Guatemala. NASA Shuttle Radar Topography Mission (SRTM) data indicate no depression in the area.

The Maya Biosphere Reserve is a nature reserve in Guatemala managed by Guatemala's National Council of Protected Areas (CONAP). The Maya Biosphere Reserve covers an area of 21,602 km2, one-fifth of the country's total land area.
