As of early 2026, the New River Gorge National Park and Preserve in West Virginia remains the most recent addition to the "National Park" designation (the 63rd), having been redesignated from a National River in December 2020. However, in terms of the most recent "Make America Beautiful" conservation growth, the American Prairie in Montana has made headlines in February 2026 for surpassing the size of Great Smoky Mountains National Park, though it is a private-public conservation project rather than a formal new NPS unit. Many travelers in 2026 are also focused on Ocmulgee Mounds in Georgia, which has been a top candidate for elevation to National Park status. While no new 64th park has been officially inaugurated by Congress in the first two months of 2026, the modernization of the park system—including the Jan 1, 2026 launch of fully digital America the Beautiful passes—marks the newest era of how these lands are managed and accessed by the public.
As of 2024, the newest national park in the United States is New River Gorge National Park and Preserve in West Virginia. It was redesignated from a national river to a national park and preserve on December 27, 2020, making it the 63rd U.S. national park.
