**月桂酸**（英文：Lauric acid），系統學名稱為**十二烷酸**（英文：dodecanoic acid），是具有 12 個碳原子鏈的飽和脂肪酸。它的分子式是 C12H24O2。具有中鏈脂肪酸的許多性質，呈白色粉末狀固體，有微弱的月桂油或肥皂的氣味。月桂酸的化學鹽和酯被稱為**月桂酸酯**（英文：laurate）。

## 自然存在

作為三酸甘油酯的成份，月桂酸在椰漿、椰子油（佔 45-52%）、月桂油及油棕籽油（佔 44-52%，留意並不是油棕果油）這些物品的脂肪含量佔約一半，但在其他物品卻絕少出現。在人類的母乳（佔總脂肪分量的 6.2%）、牛奶（佔總脂肪分量的 2.9%）及羊奶（佔總脂肪分量的 3.1%）中亦可找到月桂酸。

* _Astrocaryum murumuru_ (Arecaceae) a palm native to the Amazon - 47.5% in "murumuru butter".
* 椰子油 49%
* 非洲肉荳蔻 _Pycnanthus angolensis_
* 野生肉荳蔻 _Virola surinamensis_ 7.8–11.5%
