Sequoiadendron is a genus of evergreen trees, with two species, only one of which survives to the present:[1]
- Sequoiadendron giganteum, extant, commonly known as wellingtonia, giant redwood and giant sequoia,[2] growing naturally in the Sierra Nevada mountains of California [3]
- † Sequoiadendron chaneyi, extinct, the predecessor of Sequoiadendron giganteum, found mostly in the Nevada part of the Tertiary Colorado Plateau until the late Miocene[4]
Fossil record

Sequoiadendron fossil pollen and macrofossils may have been found as early as the Cretaceous[5] and throughout the Northern Hemisphere,[6] including locations in western Georgia in the Caucasus region.[7]
