}}Inagta Partido (Isarog Agta) is a nearly extinct Bikol language spoken by a semi-nomadic hunter-gatherer Agta (Negrito) people of the Philippines. It is found on Mount Isarog east of Naga City.
According to Lobel (2013:68),[1] there are no speakers of Inagta Partido under 60. It is a moribund language. The Ethnologue cites a report from 2000 that there were then only five speakers from an ethnic population of about 1,000.[2]
Inagta Partido has borrowed heavily from Bikol languages such as Bikol Naga and Bikol Partido, but has a non-Bikol substratum (Lobel 2013:69).[1]
