Butyl butyrate, or butyl butanoate, is an organic compound which is an ester formed by the condensation of butyric acid and butanol. It is a clear, colorless liquid that is insoluble in water, but miscible with ethanol and diethyl ether. Its refractive index is 1.406 at 20 °C.

As with other volatile esters, butyl butyrate has a pleasant aroma. It is used in the flavor industry to create sweet fruity flavors that are similar to pineapple.

It occurs in many kinds of fruit, e.g. apple, banana, berries, pear, plum or strawberry.
