The Pd atom in the title compound, [Pd(C18H14O3P)Cl(C5H8N2)], adopts a slightly distorted square-planar coordination geometry, with the metallated carbon positioned trans to the Cl atom. The crystal structure is stabilized by several weak C—H⋯O and C—H⋯Cl hydrogen-bond inter­actions. One of the phenyl rings is disordered over two almost equally occupied sites.
