Hyperion is a coast redwood (Sequoia sempervirens) in California that is the world's tallest known living tree, measured at 116.07 metres (380.8 ft) tall in 2019.

[1][3] Hyperion was discovered on August 25, 2006, by naturalists Chris Atkins and Michael Taylor.

[7] The park also houses the second-, fourth- and fifth-tallest known trees, coast redwoods named Helios, Icarus, and Daedalus, which respectively measured 377, 371 and 363 feet in 2022.

[11] However, in July 2022, the Redwood Park superintendent closed the entire area around the tree, citing "devastation of the habitat surrounding Hyperion" caused by visitors.

Its base was trampled by the overuse and as a result ferns no longer grow around the tree.
