Serian is a town, and the capital of the Serian separated on 11 April 2015 from Samarahan Division, Sarawak, Malaysia. It is located about 40 miles from Kuching. Sub-district headquarters towns are Siburan and Tebedu.
The town is known for its durians, which are popularly believed to be the best in Sarawak. This has prompted the Serian District Council to erect a giant monument to this "king of fruits" right in the middle of the market square. However, other monuments such as the tiger and the buffalo statues seem out of place as there are no tigers or buffalos in this district. The town is well connected to its rich hinterland both by road and by water and thus one can find all sorts of jungle produce available in the jungle produce market but lately, most of these produce were brought in from Kalimantan, Indonesia as the price are cheaper.
The district population was 90,763. About 65% of the population are Bidayuh. The other main ethnic groups are Iban, Chinese, and Malay.
