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