In enzymology, a glycosphingolipid deacylase (EC 3.5.1.69) is an enzyme that catalyzes a chemical reaction that cleaves gangliosides and neutral glycosphingolipids, releasing fatty acids to form the lyso-derivatives.

This enzyme belongs to the family of hydrolases, specifically those acting on carbon-nitrogen bonds other than peptide bonds, specifically in linear amides. The systematic name of this enzyme class is glycosphingolipid amidohydrolase. This enzyme is also called glycosphingolipid ceramide deacylase.
