Malonic anhydride or oxetane-2,4-dione is an organic compound with chemical formula C₃H₂O₃ or CH₂(CO)₂O. It can be viewed as the anhydride of malonic acid, or a double ketone of oxetane.

Malonic anhydride was first synthesized in 1988 by ozonolysis of diketene.^[1]^[2] Some derivatives, such as 3,3-dimethyl-oxetane-2,4-dione, are known.^[3]^[4]^[5]
