Polyvinyl acetate or PVA is a rubbery synthetic polymer. It is prepared by polymerization of vinyl acetate. Partial or complete hydrolysis of the polymer is used to prepare polyvinyl alcohol. It was discovered in Germany by Dr. Fritz Klatte in 1912.

PVA is sold, as an emulsion in water, as an adhesive for porous materials, particularly wood. It is the most commonly used wood glue, both as "white glue" and the yellow "carpenter's glue", the former also used extensively to glue other materials like paper and cloth.

It can also be used to protect cheese from fungi and humidity.
