In the title compound, C7H11Cl2NO, the piperidine ring shows a chair conformation and the bond-angle sum at the N atom is 359.9°. The H atom of the dichloromethyl group is in an eclipsed conformation with respect to the carbonyl group (H - C - C=O = - 5°). In the crystal, inversion dimers are linked by pairs of C - H⋯O hydrogen bonds between the dichloromethyl group and the carbonyl O atom, which generate R 22(8) loops. The dimers are linked into a ladderlike structure propagating in the [100] direction by short O⋯Cl [3.1084 (9) Å] contacts.
