The title compound, [RhCl(C22H34OP)2(CO)], can be described as one of a few RhI Vaska‐type complexes containing a (2‐naphth­yloxy)diphenyl­phosphine ligand and has a square‐planar geometry about the rhodium(I) metal centre, which lies on an inversion centre, so that the carbonyl and chloro ligands are disordered. The most important bond lengths and angle include Rh—P = 2.305 (1) Å, Rh—Cl = (trans CO) = 2.374 (2) Å, Rh—C (carbon­yl) = 1.818 (6) Å and Rh—C—O = 178.1 (10)°. A weak π–π inter­molecular stacking is observed, with an inter­planar distance of 3.377 (2) Å.
