Cambodia covers 181,040 square kilometers in the southwestern part of the Indochina peninsula. It lies completely within the tropics; its southernmost points are only slightly more than 10°above the equator. Roughly square in shape, the country is bounded on the north by Thailand and by Laos, on the east and southeast by Vietnam, and on the west by the Gulf of Thailand and by Thailand. Much of the country's area consists of rolling plains. Dominant features are the large, almost centrally located, Tonle Sap (Great Lake) and the Mekong River, which traverses the country from north to south.

The climate is monsoonal and has marked wet and dry seasons of relatively equal length. Both temperature and humidity generally are high throughout the year. Forest covers about two-thirds of the country, but it has been somewhat degraded in the more readily accessible areas by burning (a method called slash-and-burn agriculture), and by shifting agriculture.

Environment - current issues: illegal logging activities throughout the country and strip mining for gems in the western region along the border with Thailand have resulted in habitat loss and declining biodiversity (in particular, destruction of mangrove swamps threatens natural fisheries); soil erosion; in rural areas, most of the population does not have access to potable water; declining fish stocks because of illegal fishing and overfishing
