The National Parks Conservation Association (NPCA) is a nonprofit organization focused on protecting and enhancing America’s National Park System for current and future generations. Founded over 100 years ago, NPCA advocates for national parks, ensuring these iconic landscapes and historic sites are preserved, well-funded, and accessible to all.

NPCA's mission includes advocacy, education, and community engagement. The organization educates decision-makers about critical issues facing national parks and mobilizes over 1.6 million members and supporters to participate in campaigns and volunteer opportunities. It also provides information through newsletters and its National Parks magazine to raise awareness about park issues. NPCA integrates justice, equity, diversity, and inclusion principles into its work, promoting sustainable practices and striving to include marginalized voices in conservation efforts.
