View of Phnom Penh from above, showing the confluence of the Tonlé Sap River and Mekong, and the filled in lake of Boeung Kak.Phnom Penh is in the south-central region of Cambodia, and is fully surrounded by the Kandal province. The municipality is on the banks of the Tonlé Sap, Mekong, and Bassac Rivers. These rivers provide freshwater and other natural resources to the city. Phnom Penh and the surrounding areas consist of a typical flood plain area for Cambodia. While Phnom Penh is at 11.89 metres (39 ft) above the river, monsoon season flooding is a problem, and the river sometimes overflows its banks. Boeung Kak, Phnom Penh's largest freshwater lake, was controversially filled in 2010 to make way for property development.Climate Phnom Penh has a tropical wet and dry climate (Köppen climate classification Aw). The climate is hot year-round with only minor variations. Temperatures typically range from 22 to 35 °C (72 to 95 °F) and weather is subject to the tropical monsoons.

Phnom Penh (lit. 'Penh's hill') takes its name from the Wat Phnom (lit. 'hill temple'), or from the Funan Kingdom, which existed from the 1st to the 7th century AD in Southeast Asia and was the forerunner of the Cambodian monarchy. Legend has it that in 1372, a wealthy widow named Penh found a Koki tree floating down the Tonlé Sap River after a storm.Phnom Penh's former official name is Krong Chaktomuk Serei Mongkol (Khmer: ក្រុងចតុមុខសិរីមង្គល, lit. "city of Brahma's faces"), in its short form as Krong Chaktomuk (lit. 'city of four faces'). Krong Chaktomuk is an abbreviation of the full name, given to it by King Ponhea Yat: Krong Chaktomuk Mongkol Sakal Kampuchea Thipadei Serei Theakreak Bavar Intabat Borei Roat Reach Seima Moha Nokor (Khmer: ក្រុងចតុមុខមង្គលសកលកម្ពុជាធិបតី សិរីធរបវរ ឥន្ទបត្តបុរី រដ្ឋរាជសីមាមហានគរ ). This loosely translates as "the place of four rivers that gives the happiness and success of the Khmer Kingdom, the highest leader as well as impregnable city of the God Indra of the great kingdom".
