We compute the heavy quark potentials including relativistic corrections by using lattice QCD simulations within the quenched approximation. These results are important nonperturbative inputs of an effective field theory called potential nonrelativistic QCD, which serves for the systematic study of heavy quarkonia. Utilizing the multilevel algorithm and the transfer matrix theory, we determine the potentials at the distances ranged from 0.25 to 1.2 fm. We observe long-range nonperturbative contributions to the potentials as well as a reasonable scaling behavior with respect to the change of lattice spacing.
