Butyronitrile or butanenitrile or propyl cyanide, is a nitrile with the formula C₃H₇CN. This colorless liquid is miscible with most polar organic solvents.

Butyronitrile is mainly used as a precursor to the poultry drug amprolium.

Butyronitrile is prepared industrially by the ammoxidation of n-butanol:

Butyronitrile has been detected in the Large Molecule Heimat.
