Lubok Antu District (Malay: Daerah Lubok Antu) is a district in the Sri Aman Division of the state of Sarawak, Malaysia.[2] It borders on Indonesia and a Malaysian border crossing checkpoint is located here. The checkpoint on the Indonesian side is called the Nanga Badau Border Crossing Checkpoint located in the village of Badau, West Kalimantan. The seat of Lubok Antu District is the town of Lubok Antu.
The district has about 42,000 people; they are predominantly Ibans, and there are also some Chinese residents.[3] Most residents make their living from farming (shifting cultivation).[4]
The Batang Ai river runs through the district. There is a suspension bridge which leads to the village of Kampung Pasir. A dam completed in 1985 caused the displacement of thousands of people when their homes were flooded. In 2018 a suspension bridge at Nanga Kesit collapsed because of flooding.[5]
