肖蒲桃属（学名：Acmena），又名赛赤楠属，是桃金娘科下的一个属，为乔木或灌木植物。该属共有约11种，分布于印度、中南半岛、印度尼西亚、马来西亚和澳大利亚。

Acmena is a genus of shrubs and small trees in the myrtle family Myrtaceae. They are related to guavas. The name is derived from the Greek word for "plentiful."

The name was first validly published in 1828. The species of this genus have sometimes been treated as part of the large Old World genus Syzygium (which in turn has sometimes been included in Eugenia, although many authors limit Eugenia mostly to New World species). Several 2006 papers include Acmena in Syzygium.
