'''''o''-Toluic acid''', also '''2-methylbenzoic acid''', is an [[aromatic]] [[carboxylic acid]], with formula (CH<sub>3</sub>)C<sub>6</sub>H<sub>4</sub>(COOH). It is an isomer of [[P-Toluic acid|''p''-toluic acid]] and [[M-Toluic acid|''m''-toluic acid]]. When purified and recrystallized, ''o''-toluic acid will form needle-shaped crystals.
