山榄（学名：Planchonella obovata）为山榄科山榄属下的一个种。

Pouteria obovata is a tree in the Sapotaceae family. Confusingly, this is not the same plant that was formerly known by the same scientific name, the Andean Pouteria lucuma. The common name in Australia is the Northern Yellow Boxwood. It occurs in many parts of south-east Asia, Micronesia, and on islands of the Indian Ocean, and has local common names there.
