The geography of Mesoamerica describes the geographic features of Mesoamerica, a culture area in the Americas inhabited by complex indigenous pre-Columbian cultures exhibiting a suite of shared and common cultural characteristics. Several well-known Mesoamerican cultures include the Olmec, Teotihuacan, the Maya, the Aztec and the Purépecha. Mesoamerica is often subdivided in a number of ways. One common method, albeit a broad and general classification, is to distinguish between the highlands and lowlands. Another way is to subdivide the region into sub-areas that generally correlate to either culture areas or specific physiographic regions.
