I present the two-loop self-energy functions and pole masses for fermions inan arbitrary renormalizable field theory, in the approximation that vectorbosons are treated as massless. The calculations are done simultaneously in themass-independent \bar{MS}, \bar{DR}, and \bar{DR}' renormalization schemes,with a general covariant gauge fixing, and treating Majorana and Dirac fermionsin a unified way. As examples, I discuss the two-loop strong interactioncorrections to the gluino, neutralino, chargino, and quark pole masses inminimal supersymmetry. All other two-loop contributions to the fermion polemasses in softly broken supersymmetry can also be obtained as special cases ofthe results given here, neglecting only the electroweak symmetry breaking scalecompared to larger mass scales in two-loop diagrams that involve W or Z bosons.
