The giant sequoia (Sequoiadendron giganteum) is the world's most massive tree, and arguably the largest living organism on Earth. It is neither the tallest extant species of tree (that distinction belongs to the coast redwood), nor is it the widest (that distinction belongs to the baobab tree or Montezuma cypresses), nor is it the longest-lived (that distinction belongs to the Great Basin bristlecone pine). However, with a height of 87 meters (286 ft) or more, a circumference of 34 meters (113 ft) or more, an estimated bole volume of up to 1,490 cubic meters (52,500 cu ft), and a documented lifespan of 3266 years, the giant sequoia is among the tallest, widest, and longest-lived of all organisms on Earth.
