The Semang are an ethnic-minority group of the Malay Peninsula. They live in mountainous and isolated forest regions of Perak, Pahang, Kelantan and Kedah of Malaysia and the southern provinces of Thailand. The Semang are among the different ethnic groups of Southeast Asia who, based on their dark skin and other perceived physical similarities, are sometimes referred to by the superficial term Negrito.
They have been recorded since before the 3rd century. They are ethnologically described as nomadic hunter-gatherers.
The Semang are grouped together with other Orang Asli groups, a diverse grouping of several distinct hunter-gatherer populations. Historically they preferred to trade with the local population. For more than one thousand years, some of the Semang people remained in isolation while others were either subjected to slave raids or forced to pay tribute to Southeast Asian rulers.
