We calculate the pole mass of the gluino as a function of the running parameters in the lagrangian, to O(alpha_s^2) in SUSY QCD. The correction shifts the pole mass from the running mass by typically 1-2 %. This shift can be larger than the expected accuracy of the mass determination at future colliders, and should be taken into account for precision studies of the SUSY breaking parameters. The effects of other corrections are breifly commented.
