Notes: Redwood National Park, America's 34th national park, was established on October 2, 1968 when President Lyndon B. Johnson signed legislation which preserved 91 mi² (235 km²) of old-growth coast redwood forest in Northern California and associated creeks, rivers, and coastline for purposes of public inspiration, enjoyment, and scientific study. The new park boundary encompassed three existing California state parks: Jedediah Smith Redwoods State Park, Del Norte Coast Redwoods State Park, and Prairie Creek Redwoods State Park.

On March 27, 1978, Redwood National Park nearly doubled in size, expanding by 75 mi² (194 km²), when President James E. Carter signed legislation which preserved additional tracts of coast redwood forest (much of which had already been logged) along Redwood Creek and its tributaries and protected existing tracts from damaging effects of logging operations upslope and upstream to create a more meaningful Redwood National Park for the use and enjoyment of visitors. In 1994, the National Park Service and California Department of Parks and Recreation agreed to manage Redwood National Park and the three neighboring state redwood parks together as Redwood National and State Parks.

On December 20, 2005, Redwood National Park expanded for the last time after President George W. Bush signed legislation which added the 39 mi² (101 km²) Mill Creek Addition, which included the upper Mill Creek and Rock Creek watersheds, to the park. On September 5, 1980, the United Nations designated Redwood National and State Parks a World Heritage Site and, on June 30, 1983, declared the parks part of the California Coast Ranges Biosphere Reserve.

Today, Redwood National and State Parks encompass more than 206 mi² (534 km²) of terrain and include nearly 61 mi² (158 km²) of old-growth coast redwood forest which represent 45% of remaining old-growth coast redwoods on Earth. Redwood National Park contains more than 200 mi (322 km) of hiking trails and receives over 500,000 visitors annually.

Redwood National Park includes the world's tallest tree (Hyperion), 4 former world's tallest trees (Harry Cole, Helios, Howard Libbey, and Nugget), the oldest coast redwood (undisclosed), the tallest tree discovered by light detection and ranging (LiDAR) (Orion), the 3rd (Emerald Giant) and 5th (Nugget) fastest-growing redwoods, 9 of the 30 tallest trees on Earth (Daedalus, Gulch Tower, Harry Cole, Helios, Hyperion, Icarus, Nugget, Orion, and Paul Zahl), and 3 of the 30 largest coast redwoods (ARCo Giant, Melkor, and Redwood Creek Giant). The park contains 36 trees taller than 350 ft (106.68 m), 13 trees taller than 360 ft (109.73 m), 5 trees taller than 370 ft (112.78 m), 1 tree taller than 380 ft (115.82 m), 6 trees larger than 20,000 ft³ (566 m³), 3 trees larger than 25,000 ft³ (708 m³), and 2 trees larger than 30,000 ft³ (850 m³).

Hyperion is the tallest tree and Melkor is the largest tree in Redwood National Park.
