Hyperion is the name of a coast redwood (Sequoia sempervirens) in Northern California that was measured at 115.92 m (380.3 ft), which ranks it as the world's tallest known living tree. After 2013, research reports omit tree names, and previously known tall redwoods grew, fell, or lost height.
Hyperion was discovered August 25, 2006, by naturalists Chris Atkins and Michael Taylor. The tree was verified as standing 115.55 m (379.1 ft) tall by Stephen Sillett. The tree was found in a remote area of Redwood National and State Parks purchased in 1978. The tree is located at 41.20491 N and 124.01556 W, near Tom McDonald Creek and is accessible from the Tall Trees trailhead. The tree is estimated to contain 530 m3 (18,600 cu ft) of wood. Sillett estimates the tree to be 600 years old while others report it to be roughly 700–800 years old.
