Sequoia is a genus of redwood coniferous trees in the subfamily Sequoioideae of the family Cupressaceae. The only extant species of the genus is Sequoia sempervirens in the Northern California coastal forests ecoregion of Northern California and Southwestern Oregon in the United States.^[1]^[2] The two other genera in the subfamily Sequoioideae, Sequoiadendron and Metasequoia, are closely related to Sequoia. It includes the tallest trees, as well as the heaviest, in the world.

Several extinct species have been named from fossils, including Sequoia affinis (Western North America), Sequoia chinensis (no valid reference, identification uncertain) of China, Sequoia langsdorfii (reclassified as Metasequoia),^[3] Sequoia dakotensis (reclassified as Metasequoia)^[3] of South Dakota (Maastrichtian), and Sequoia magnifica (petrified wood from the Yellowstone National Park area).
