Sequoiadendron is a genus of evergreen trees, with three species, only one of which survives to the present:

• Sequoiadendron giganteum, extant, commonly known as wellingtonia, giant redwood and giant sequoia, growing naturally in the Sierra Nevada mountains of California
• † Sequoiadendron chaneyi, the predecessor of Sequoiadendron giganteum, found mostly in the Nevada area of the Tertiary Colorado Plateau until the late Miocene
• †Sequoiadendron tchucoticum Late Cretaceous; Enmyvaam River Basin, Russia

Fossil record

Sequoiadendron fossil pollen and macrofossils may have been found as early as the Late Cretaceous and throughout the Northern Hemisphere, including locations in western Georgia in the Caucasus region.
