Ethenol, also called vinyl alcohol, hydroxyethene or hydroxyethylene, is an alcohol with chemical formula C₂H₄O (H2C=CHOH) and CAS number 557-75-5. Normally it exists as the tautomer acetaldehyde. For this reason the thermoplastic polyvinyl alcohol (PVA or PVOH) which would be derived from this monomer, is made indirectly by polymerization of vinyl acetate and then hydrolysis of the polyvinyl acetate.

Between May and June 2001, astronomers A. J. Apponi and Barry Turner discovered vinyl alcohol in the molecular cloud Sagittarius B using the National Science Foundation's 12 meter radio telescope at the Kitt Peak National Observatory.
