Lundu is a district located in the Northwest of Kuching Division of Sarawak, Malaysia, and borders with Indonesian Province of West Kalimantan.

In the middle of the eighteenth century a group of Bidayuh people from near Bau migrated and settled on the west bank of the Batang Kayan, where Kampong Stunggang Melayu now stands.

They came to be called the Dayak Lundu, and though the last member of the tribe died in the 1960s, you can still see the grove of durian trees they planted.

His children are very famous such as Dato Terawoh in Kota Samarahan and Datu Godam (Saribas) who use the title of Abang.

Towards the close of the eighteenth century three groups of people at the same time came separately to make their homes in Lundu.

As the Iban were coming to Lundu from the east, Chinese and Selako settlers were arriving from the west, over the hills that separate Sarawak from what is now Indonesian Borneo.

The road from Bau to Lundu was completed in that year and regular bus service began.

On March 26, 1972,The North Kalimantan Communist Party (NKCP) ambushed a convoy of the 7th Royal Ranger Regiment in Lundu, Sarawak, killing 15 soldiers.

Corporal Jamaluddin quickly arrived with a Ferret armoured vehicle and opened fire, causing the insurgents to retreat.In response, the 7th Royal Ranger Regiment launched a large-scale operation, killing several insurgents and seizing weapons.

Centre for Technology Excellence Sarawak (CENTEXS) set up a hospitality and tourism academy in Lundu in December 2022 to upskill and reskill school leavers, industry employees, and university graduates.

Siar beach is located to the west of the Lundu town, within Pandan village.
