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.

The General Sherman was named after the American Civil War general William Tecumseh Sherman, in 1879 by naturalist James Wolverton, who had served as a lieutenant in the 9th Indiana Cavalry under Sherman. In 1931, following comparisons with the nearby General Grant tree, General Sherman was identified as the largest tree in the world. One result of this process was that wood volume became widely accepted as the standard for establishing and comparing the size of different trees.
