The Kingdom of Cambodia (Khmer: transliterated: Preăh Réachéanachâkr Kâmpŭchea) is a country in Southeast Asia with a population of almost 15 million people, with Phnom Penh being the capital city. Cambodia is the successor state of the once powerful Hindu and Buddhist Khmer Empire, which ruled most of the Indochinese Peninsula between the eleventh and fourteenth centuries.

A citizen of Cambodia is usually identified as "Cambodian" or "Khmer", which strictly refers to ethnic Khmers. Most Cambodians are Theravada Buddhists of Khmer extraction, but the country also has a substantial number of predominantly Muslim Cham, as well as ethnic Chinese, Vietnamese and small animist hill tribes.
