Kampong Chhnang (Central Khmer: កំពង់ឆ្នាំង in Central Khmer pronounced as /kɑmpɔŋ cʰnaŋ/) is the capital city of Kampong Chhnang Province, in central Cambodia.
It is located just west of the Tonlé Sap River and is a noted port. The small city is connected to Phnom Penh by a national highway route and railway. Phnom Kong Rei is a landmark located north of the city across the Tonle Sap River.
The economy of the area is dominated by rice production.[2] Until recently, many locals lived in floating fishing villages during the high-water monsoon season.The last of these flaoting villages was dismantled at the end of 2022.[3]
