Deen Maar Indigenous Protected Area is an Indigenous Protected Area (IPA) located in south-west Victoria, Australia, on land bounded by the Eumeralla River and Bass Strait.

In 1842 Deen Maar was the site of conflict between the Indigenous people of the area and European colonists.

[2] The property was purchased in 1993 by ATSIC for the Framlingham Aboriginal Trust with the intention that it become an Indigenous Protected Area, and it was granted this status in 1999.

The country consists of limestone ridges, wetlands, lakes, and sand dunes.

It is the traditional home of the Peek Whurrong speakers of the Dhauwurdwurung (Gunditjmara) nation.
