Massachusett Tribe at Ponkapoag

The Massachusett Tribe at Ponkapoag is a cultural heritage group that claims descendancy from the Massachusett people, an Indigenous people of the Northeastern Woodlands.

While they identify as a Native American tribe, they are unrecognized, meaning they are neither a federally recognized tribe nor a state-recognized tribe.
