In this letter, we study quasinormal modes of regular non-minimal Einstein-Yang-Mills (EYM) black holes. We mainly consider the scalar field perturbation and axial gravitational perturbation of the EYM black hole. The corresponding effective potential is derived by solving the field equations. The quasinormal ringing of EYM black hole under scalar field perturbation and axial gravitational perturbation is given through time domain integration. Our results show that the magnetic charge Q will reduce the damping rate of the gravitational waves generated by the EYM black hole after being disturbed.
