The following is the text of a February 24, 2026, press release from the National Congress of American Indians.

WASHINGTON D.C. — The National Congress of American Indians (NCAI) mourns the passing of JoAnn K. Chase (Mandan, Hidatsa and Arikara), a visionary leader and former Executive Director who strengthened NCAI’s national presence and advanced the rights of Tribal Nations across the United States. NCAI extends its deepest condolences to her family, the Mandan, Hidatsa and Arikara Nation, and all who were impacted by her leadership, mentorship, and friendship.

JoAnn Chase served as Executive Director of NCAI and the NCAI Fund from 1994 to 2001. During her tenure, she transformed the organization’s capacity and reach, tripling its staff, operating budget, and Tribal membership. Under her leadership, NCAI became a stronger, more visible, and more effective advocate for Tribal sovereignty in the nation’s capital. She worked closely with Tribal Leaders, Congress, the Executive Branch, and national civil rights organizations to advance policies protecting Tribal self-determination and the rights of Tribal Nations.

“The role of Executive Director is both a privilege and an earned trust – one that requires listening, humility, and unwavering commitment to Tribal sovereignty,” said NCAI Executive Director Larry Wright Jr. “JoAnn carried that trust with honor. Her leadership expanded NCAI’s capacity and strengthened our voice in Washington, and her legacy continues to guide the work we do for Tribal Nations today.”

Prior to serving as Executive Director, Chase held multiple leadership roles at NCAI, including Director of Governmental Affairs and Policy Analyst. Across these positions, she helped design and implement NCAI’s governmental affairs program, shaped public policy advocacy, and strengthened the organization’s legislative engagement on behalf of Tribal governments.

Throughout her distinguished career, Chase remained committed to building inclusive institutions and strengthening Native leadership. Following her tenure at NCAI, she served as Director of the American Indian Environmental Office in the U.S. Environmental Protection Agency, where she provided national leadership on environmental protection and Tribal consultation. She later continued her work in philanthropy, policy, and the arts, championing initiatives that expanded opportunity and representation for Indigenous Peoples and communities of color.

NCAI honors JoAnn Chase’s enduring contributions to Tribal Nations and to the generations of Native leaders who continue the work she helped strengthen. Her legacy lives on in the institutions she helped build and in the continued advancement of Tribal sovereignty across Indian Country.
