'The Glorious and Auspicious') is a municipality (krong) in the centre of Banteay Meanchey province, in north-western Cambodia.

Cambodia's main railway line from Phnom Penh to Poipet enters the municipality from the south and exits to the west.

However, it has one of the largest municipality populations in the province due to its central location and access to transport infrastructure.

National Highway 6 which begins in Phnom Penh also has its terminus at Sisophon town in Serei Saophoan.

National road 56 begins at Sisophon town in the centre of the municipality and runs north east to Samraong in Oddar Meanchey province.

A boot camp-style rehabilitation centre, chiefly for those addicted to drugs, is located within Serei Saophoan district, in Sisophon town.

At the centre residents receive compulsory military training, massive amounts of exercise and self-criticism sessions 7 days per week for a minimum of five months.
