Methuselah is a 4,856-year-old[1] Great Basin bristlecone pine (Pinus longaeva) tree growing high in the White Mountains of Inyo County in eastern California.

Methuselah was 4,789 years old when sampled in 1957[13] by Edmund Schulman and Tom Harlan,[1] with an estimated germination date of 2833 BC.

Dendrochronologist Matthew Salzer of the University of Arizona has been unable to reproduce Schulman's age estimate, due to a missing core.

A dendrochronology, based on these trees and other bristlecone pine samples, extends back to about 9000 BC, albeit with a single gap of about 500 years.

[20][3] An older bristlecone pine was reportedly discovered by Tom Harlan in 2009, based on a sample core collected in 1957.
