The Bajau are a Moro indigenous ethnic group of Maritime Southeast Asia. The Bajau live a seaborne lifestyle, and use small wooden sailing vessels such as the perahu and vinta.

The Bajau are traditionally from the many islands of the Sulu Archipelago in the Philippines, as well as parts of the coastal areas of Mindanao and northern Borneo. In the last 50 years, many of the Filipino Bajau have migrated to neighbouring Malaysia and the northern islands of the Philippines, due to the conflict in the Autonomous Region in Muslim Mindanao. As of 2007, they were the second-largest ethnic group in the Malaysian state of Sabah, making up 13.4% of the total population. Groups of Bajau have also migrated to Sulawesi and North Kalimantan in Indonesia, although their exact population is unknown.
