3-Methylsalicylic acid is an organic compound with the formula CH3C6H3(CO2H)(OH). It is a white solid that is soluble in basic water and in polar organic solvents. At neutral pH, the acid exists as 3-methylsalicylate Its functional groups include a carboxylic acid and a phenol group. It is one of four isomers of methylsalicylic acid.

It is produced by carboxylation of sodium o-cresolate:[1][2]

CH3C6H4ONa + CO2 → CH3C6H3(CO2Na)OH
