Cerotic acid, or hexacosanoic acid, is a 26-carbon long-chain saturated fatty acid with the chemical formula CH₃(CH₂)₂₄COOH. It is most commonly found in beeswax and carnauba wax, and is a white crystalline solid.

Cerotic acid is also a type of very long chain fatty acid that is often associated with the disease adrenoleukodystrophy, which involves the excessive saturation of unmetabolized fatty acid chains, including cerotic acid, in the peroxisome. [In the chem box it is shown folded only because of lack of space. In fact, it is a straight-chain, saturated fatty acid.]
