Kampong Chhnang (Khmer: កំពង់ឆ្នាំង [kɑmpɔŋ cʰnaŋ]; meaning 'Port of Pottery') is one of the central provinces (khaet) of Cambodia.

It is in the alluvial plain of central Cambodia and is drained by the Tonle Sap, a tributary of the Mekong river.

The capital city of Phnom Penh has grown until it actually encompasses the provincial border of Kampong Chhnang.

Archaeological remains from the area have revealed among many other findings artifacts from Dvaravati, a former kingdom in present-day Thailand, dating to the 6th through 11th centuries.

[7] Kampong Chhnang province centuries ago was a coastal city on the route between China and India; due to sedimentation from the Mekong river, the coast line moved much farther to sea.
