The Senoi are a group of Malaysian peoples classified among the Orang Asli, the indigenous peoples of Peninsular Malaysia. They are the most numerous of the Orang Asli and widely distributed across the peninsula. The Senois speak various branches of Aslian languages, which in turn form a branch of Austroasiatic languages. Many of them are also bilingual in the national language, the Malaysian language.

Orang Asli are a heterogeneous indigenous population forming a national minority in Malaysia. They are the oldest inhabitants of Peninsular Malaysia.
