Map - Krouch Chhmar District (Srŏk Kroch Chhmar)

Krouch Chhmar District (ស្រុកក្រូចឆ្មារ) is a district (srok) located in Tboung Khmum Province, Cambodia. The district capital is Krouch Chhmar town located around 35 kilometres north east of the provincial capital of Kampong Cham by water. The Mekong River forms western and northern borders of the districts and includes the Mekong island of Koh Pir in its area. Not surprisingly, communities in this isolated district are mostly clustered along the banks of the river and boats are an important form of transport.

The district is easily accessed by boat from neighboring Kampong Cham Province. Road access however, is more problematic. The district can only be accessed by vehicles via Chhloung town, Chhloung District in Kratie Province. The main road from the district capital of Krouch Chhmar runs along the Mekong for around 35 kilometres of secondary road to an intersection with National road 73 at Chhloung. From here it is around 18 kilometres north to Kratie or 30 kilometres south to the intersection with National Highway 7. From this intersection in Dambae District is it a further 34 kilometres west to the town of Kampong Cham.

Krouch Chhmar district is also the birthplace of Cambodia's first lady, Bun Rany the wife of Prime Minister Hun Sen. Bun Rany was born in 1954 in Roka Khnaor, Krouch Chhmar district, the fourth of five children from a farming family. Bun Rany joined the Khmer Rouge in 1970, after the coup by Lon Nol and received medical training. In 1975, when Phnom Penh fell to the communists she was the director of Krouch Chhmar district hospital, deep in the "liberated zone" (the zone controlled by the Khmer Rouge).
