In the title salt, C11H15ClNO+·C7H5O2−, the dihedral angle between the mean planes of the chlorophenyl ring of the cation and the benzene ring of the anion is 74.4 (1)°. In the cation, the six-membered piperazine ring adopts a chair conformation. The crystal packing is stabilized by intermolecular N—H⋯O and O—H⋯O hydrogen bonds, and weak intermolecular C—H⋯O, C—H⋯Cl and C—H⋯π interactions.
