The Dumpas are an indigenous ethnic group residing in Sabah, Malaysia.

They reside in the villages of Rancangan Nangoh and Perancangan of the Beluran district in the Sandakan Division.

Their language (ISO 639-3 dmv) belongs to the Paitanic branch of the Austronesian language family.

The language is dying out as a result of intermarriage with other groups, and since native speakers also use Tambanuo in their daily conversation.
