Ong Be (), also known as Bê, or Vo Limgao (臨高, Lin'gao) in Chinese, is a language spoken by 600,000 people, 100,000 of them monolingual, on the north-central coast of Hainan Island, including the suburbs of the provincial capital Haikou. The language is taught in primary schools and broadcast on the radio. Ong Be is a Kradai language, but it has no close relatives and its relationship within that family has not been determined.
