'''''Pterospermum''''' is a genus of flowering plants in the mallow family Malvaceae. Its species are tropical trees that range from southern China across tropical Asia.
Traditionally included in the family Sterculiaceae, it is included in the expanded Malvaceae in the APG and most subsequent systematics. ''Pterospermum'' is based on two Greek words, "Pteron" and "Sperma," meaning "winged seed."
Some species are grown ornamentally while others are valued for their timber.
