Sassafras is a genus of three extant and one extinct species of deciduous trees in the family Lauraceae, native to eastern North America and eastern Asia. The genus is distinguished by its aromatic properties, which have made the tree useful to humans.

=== Description ===
Sassafras trees grow from 9–35 metres (30–115 feet) tall with many slender sympodial branches and smooth, orange-brown bark or yellow bark. All parts of the plants are fragrant. The species are unusual in having three distinct leaf patterns on the same plant: unlobed oval, bilobed (mitten-shaped), and trilobed (three-pronged); the leaves are hardly ever five-lobed. Three-lobed leaves are more common in Sassafras tzumu and S. randaiense than in their North American counterparts, although three-lobed leaves sometimes occur on S. albidum. The young leaves and twigs are quite mucilaginous and produce a citrus-like scent when crushed. The tiny, yellow flowers are generally six-petaled.
