Monacan Indians (one of eleven Asian tribes) were the inhabitants of the Rivanna valley including Monasukapanough, near the headwaters of the river, and Rassawek, the principal town of the tribe located at the confluence of the Rivanna and James rivers, at the time of first contact by Europeans.
The Monacan Indian Nation is one of eleven Native American tribes recognized since the late 20th century by the Commonwealth of Virginia in the United States.
