To provide a method for producing the subject compound by catalytic hydrogenation of 2,2,6,6-tetramethyl-4-piperidone and enabling circulating reuse of the hydrocarbon solvent used in the reaction without affecting the quality of the final product at all.

In the method for producing 2,2,6,6-tetramethyl-4- hydroxypiperidine by hydrogenating 2,2,6,6-tetramethyl-4-piperidone in the presence of a hydrogenation catalyst in a hydrocarbon solvent, the mother liquid after recovering the 2,2,6,6-tetramethyl-4-hydroxypiperidine crystallized from the reaction mixture after the reaction is treated with an acid and then circulated and reused as a solvent for the reaction.
