云南拟单性木兰（学名：Parakmeria yunnanensis）为木兰科拟单性木兰属下的一个种。

Parakmeria yunnanensis is a species of tree in the family Magnoliaceae, native to evergreen broad-leaved forests in eastern Asia, southern China and Indochina.

Richard Figlar notes that the Parakmeria yunnanensis is "often cultivated as street trees in their native Yunnan because of their 'Gallery Pear-type' growth habit and their exceptionally glossy evergreen foliage". He also notes that "their flowers are not as profuse and are less showy than those of other magnolia species".
