Batak is a collective term used to identify a number of ethnic groups found in the highlands of North Sumatra Indonesia. Their heartland lies to the west of Medan centred on Lake Toba. In fact the "Batak" include several groups with distinct, albeit related, languages and customs (adat).

The Batak are one of about 70 indigenous peoples of the Philippines. They are located in the northeastern portions of Palawan, a relatively large island in the southwest of the archipelago. There are only about 500 Batak remaining.
