Semporna is a town located in Tawau Division, in the east coast of Sabah, Malaysia on the island of Borneo. Its population was estimated to be around 133,000 in 2006.
Semporna was founded soon after the British North Borneo Company established Sandakan, and initially settled by Chinese traders. The name Semporna means place of rest and was given after the British quelled resistance from the local Bajaus in the mid-1880s, changing it from Tong Talun. Another story is that Semporna was called place to settle or meeting place by four admirals – Panglima Kabogan, Panglima Bum-Bum, Panglima Simunul and Panglima Abdullah.
The majority of the population is Bajau, many of whom live in sprawling stilt villages over the water on the outskirts of town. Semporna is located at the tip of Semporna Peninsula around Lahad Datu Bay (also known as Darvel Bay), and is visited by tourists as a base for scuba diving or snorkeling trips to Pulau Sipadan (Sipadan Island), some 36 kilometers southeast of town.
Marine products are still the mainstay of the local economy. Pearl culturing is a major component of this industry.
