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 initial settlement of Phnom Penh is believed to have been established since the 5th century AD, according to the discovery of kiln site in Choeung Ek commune of Dangkao district, southern part of central Phnom Penh in the 2000s. Choeung Ek archaeological site was one of the largest kiln pottery center in Cambodia and the earliest known kiln sites in Southeast Asia to produce the ceremonial vessels known as kendi from 5th to 13th century. Archaeologists stated that a large community is surrounded by a circular earthwork structure that is 740 metres in diameter and 4 metres high, built in the 11th century. There are remnants of other village infrastructure, irrigation system, inscription, Shiva linga and a brick temple foundation and its ornate remains which dated back to Funan era.First recorded a century after it is said to have taken place, the legend of the founding of Phnom Penh tells of a local woman, Penh (also referred to as Daun Penh (Lady Penh in Khmer), living at Chaktomuk, the future Phnom Penh. It was the 14th century, and the Khmer capital was still at Angkor near Siem Reap 350 km (217 mi) to the north. Gathering firewood along the banks of the river, Lady Penh spied a floating koki tree in the river and fished it from the water. Inside the tree she found four Buddha statues and one of Vishnu.Phnom Penh from east drawn in 1887.Stupa of King Ponhea Yat on the top of Wat PhnomThe discovery was taken as a divine blessing, and to some a sign that the Khmer capital was to be brought to Phnom Penh from Angkor. To house the new-found sacred objects, Penh raised a hill on the west bank of the Tonle Sap River and crowned it with a shrine, later known as Wat Phnom at the north end of central Phnom Penh. "Phnom" is Khmer for "hill" and Penh's hill took on the name of the founder, and the area around it became known after the hill.… មើលលើវីគីភីឌា

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".
