Liquidambar is a genus of large deciduous trees (about 25 to 40 m tall) grown for their star-shaped leaves, which turn brilliant red, orange, yellow or purple in autumn, and for their spiky gumball fruit. The American sweetgum (Liquidambar styraciflua) is the most widely planted member, and the trees need full sun and deep, moist soil to thrive.

They were formerly often treated as a part of the Hamamelidaceae. They are native to southeast and east Asia, the eastern Mediterranean and North America. They are decorative deciduous trees that are used in the wood industry and for ornamental purposes.
