Peam Ro (Khmer: ស្រុកពាមរក៏, pronounced [piəm.rɔː]) is a district located in Prey Veng Province, in south eastern Cambodia.

It is bordered with Peam Chor and Preah Sdach districts to the south, Ba Phnum and Svay Antor districts to the east, and Krong Prey Veng and Kampong Leav to the north.

Mekong River stretches along the border between PMR and LDK dividing the area into two different districts.

Most communes in this low land district are clustered along the banks of the river, and therefore boats are an important form of transport during rainy season.

The district capital is at Neak Leung town on National Highway 1.
