The Renewable Natural Resources Foundation (RNRF) is an I.R.C. §501(c)(3) nonprofit, public policy research organization founded in 1972 in Washington, District of Columbia, in the United States. RNRF was established as a consortium of scientific, professional, educational, design, and engineering organizations whose primary purpose was advancing science, applying science, and public education in managing and conserving renewable natural resources.

The mission of RNRF is to advance interdisciplinary science, understanding, and stewardship of renewable natural resources by fostering interdisciplinary activities and synergy among professional, scientific, and educational organizations, and through public education.

RNRF has been advancing its mission through various programs, including awards, congresses, roundtables, and publications. Through diligent stewardship and generous donations, RNRF amassed considerable resources. In 2023, the board moved to re-imagine RNRF as a grant funding organization, leveraging the organization's resources to function as an endowment. The first request for proposals for grant applications is expected in the second quarter of 2025 – stay tuned!
