The quinuclidinium cation of the title compound, C(7)H(14)NO(+)·Cl(-), shows a twist along the C-N pseudo-threefold axis, with N-C-C-C torsion angles of -16.0 (1), -16.9 (1) and -15.6 (1)°. The crystal structure is stabilized by N-H⋯Cl and O-H⋯Cl hydrogen bonds, forming infinite chains along the a and b axes.
