General Sherman is a giant sequoia (Sequoiadendron giganteum) tree located in the Giant Forest of Sequoia National Park in Tulare County, in the U.S. state of California. By volume, it is the largest known living single stem tree on Earth.

While the General Sherman is the largest currently living tree, it is not the largest historically-recorded tree. The Crannell Creek Giant, a coast redwood (Sequoia sempervirens) near Trinidad, California, is estimated to have been 15 to 25% larger than the General Sherman tree by volume. That tree was cut down in the mid-1940s. Another larger coast redwood, near 90,000 cubic feet, the Lindsey Creek tree, was reported in a 1905 Humboldt Times Standard article.
