Hyperion is a coast redwood (Sequoia sempervirens) in California that is considered the world's tallest known living tree, measuring 115.92 m (380.3 ft).[2]

Hyperion was discovered on August 25, 2006, by naturalists Chris Atkins and Michael Taylor.[3] The tree was verified as standing 115.55 m (379.1 ft) tall by Stephen Sillett. It was found in a remote area of Redwood National Park purchased in 1978.[4] It is estimated to contain 530 m3 (18,600 cu ft) of wood.[5] The park also houses the second and third known tallest trees, named Helios and Icarus.[6] Hyperion is estimated to be 700 to 800 years old.[7]

The exact location of the Hyperion tree is nominally secret but is available via internet search.[8] In July 2022, the Redwood Park superintendent closed the entire area around the tree, citing "devastation of the habitat surrounding Hyperion" caused by visitors.[1][9]

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