2-Pyrrolidone (2-pyrrolidinone) is an organic compound consisting of a five-membered lactam. It is a colorless liquid used in industrial settings as a high-boiling non-corrosive polar solvent for a wide variety of applications. It is miscible with a wide variety of other solvents including water, ethanol, diethyl ether, chloroform, benzene, ethyl acetate, and carbon disulfide.

2-Pyrrolidone is an intermediate in the manufacture of polymers such as polyvinylpyrrolidone and polypyrrolidone.

A variety of pharmaceutical drugs are 2-pyrrolidone derivatives including:
