鹅掌楸属，（学名：Liriodendron） ，木兰科树木，根据其叶子的形状，中国形象地称之为“马褂树”，而西方则称为“郁金香树”(Tulip Tree)，下分鹅掌楸（Liriodendron chinense）和北美鹅掌楸（Liriodendron tulipifera）两种。

Liriodendron /ˌlaɪriəˈdɛndrən, ˌlɪr-, -ioʊ-/ is a genus of two species of characteristically large deciduous trees in the magnolia family (Magnoliaceae).

These trees are widely known by the common name tulip tree or tuliptree for their large flowers superficially resembling tulips. The Latin Liriodendron actually means "lily tree",. The tulip tree is sometimes referred to as "tulip poplar" or "yellow poplar", and the wood simply as "poplar", although Liriodendron is not closely related to the true poplars, but is more closely related to magnolia trees. The tree is also called canoewood, saddle-leaf tree, and white wood.
