sec-Butylamine is an organic chemical compound (specifically, an amine) with the formula CH3CH2CH(NH2)CH3, and occurs as a colorless liquid. sec-Butylamine is one of the four isomeric amines of butane, the others being n-butylamine, tert-butylamine and isobutylamine. It is very harmful to aquatic organisms.

sec-Butylamine is used as a fungicide and is considered a high production volume chemical. It is undergoing comprehensive review by the American Chemistry Council's Amines Panel as part of the Primary Amines Category.

sec-Butylamine is one of the isomers of butylamine. It is chiral and therefore can exist in either of two enantiomeric forms.

This compound is moderately toxic, as well as flammable and corrosive.
