sec-Butylamine is an organic chemical compound (specifically, an amine) with the formula CH3CH2CH(NH2)CH3. It is a colorless liquid. sec-Butylamine is one of the four isomeric amines of butane, the others being n-butylamine, tert-butylamine, and isobutylamine. sec-Butylamine is chiral, this simplest chiral amine, in fact. The compounds has been resolved into individual enantiomers by formation of the diastereomeric tartrate salts.

sec-Butylamine is used in the production of some pesticides.
