Nonadecylic acid, or nonadecanoic acid, is a 19-carbon saturated fatty acid with the chemical formula CH₃(CH₂)₁₇COOH. It forms salts called nonadecylates. Nonadecylic acid can be found in fats and vegetable oils, although it is rare.^{[citation needed]}

It is also present in the world of insects as the major constituent of the substance secreted by soldiers of the termite Rhinotermes marginalis for defence purposes.^[2]

Nonadecanoic acid has found applications in the field of metal lubrication.^[3]

The compound can be prepared by permanganate oxidation of 1-eicosene.^[4]
