Butanoa C4H10 formula kimikoa duen gas bat da. Lau karbono atomo dituen alkano bat da. Terminoa bi isomeroentzat erabil daiteke, baina IUPACen arabera n-butanoarentzat bakarrik erabil daiteke, bestea metilpropanoa edo isobutanoa delako. Butanoa oso sukoia da, kolorgea eta oso erraz likidifika daitekeen gasa.
