In the title molecule, C10H17PSe, the P atom has a distorted tetrahedral environment resulting in an effective cone angle of 165°. The benzene ring makes dihedral angles of 70.04 (8) and 77.28 (8)° with the phenyl rings, while the dihedral angle between the phenyl rings is 62.95 (8)°. In the crystal, molecules are linked by C-H interactions.
