The Office of Native American Affairs (ONAA) is within the Office of the Director of the National Park Service (NPS). The ONAA represents NPS-Tribal Relations and supports policy review, implementation, and a robust working relationship with Native American, Native Hawaiian, Pacific Islander, and Alaska Native communities. 

The ONAA is led by the Native American Affairs Liaison, who supports NPS staff with training, consultation guidance, and technical support. The Native American Affairs Liaison also supports tribal governments and Indigenous people in their work with NPS on multiple topics, including park policy, access, youth engagement, partnerships, and collaborative agreements with self governance Tribes.
