The Ida'an are an ethnic group of Borneo, residing primarily in the Lahad Datu, Kinabatangan, and Sandakan districts on the east coast of Sabah, Malaysia. Their current population is estimated to be around 6000 (1987 est), but it appears that they once inhabited a much larger along the east Sabah coast than present. For centuries, the Ida’an have owned exclusive rights to the collection of edible bird's nests in the limestone caves of the region, notably the Madai Caves. Most Ida'an are Moslem, but a small sub-group called the Bega'ak (population 1,500 in 1987) remains animist.
