Example of redwoods in Redwood National and State Parks (Hyperion not pictured)

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.[1] 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.[2] 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.[3] The tree is located at 41.20491 N and 124.01556 W, near Tom McDonald Creek and is accessible from the Tall Trees trailhead.[4] The tree is estimated to contain 530 m3 (18,600 cu ft) of wood.[5] Sillett estimates the tree to be 600 years old[6] while others report it to be roughly 700–800 years old.[7]

Researchers stated that woodpecker damage at the top may have prevented the tree from growing taller.[7]

In February 2012, Hyperion was featured in the BBC Radio 4 documentary James and the Giant Redwoods by James Aldred.[8]
