Broussonetia is a genus of four species (including one hybrid species) of trees in the family Moraceae, native to eastern Asia.

[1] These four species have high-quality fiber which consist of more than 90% of cellulose.

One of these is the paper mulberry (Broussonetia papyrifera), whose bark fiber is used to make traditional paper in China, Korea, and Japan.

This species has been widely introduced and has become invasive in some areas.

Four species and one natural hybrid are accepted:[1] Five fossil fruits of †Broussonetia pygmaea have been extracted from borehole samples of the Middle Miocene freshwater deposits in Nowy Sacz Basin, West Carpathians, Poland.
