We analyze the possible magnitude of the supersymmetric contribution to g(mu) - 2 in a flipped SU(5) GUT model. Unlike other GUT models which are severely constrained by universality relations, in flipped SU(5) the U(1) gaugino mass and the soft supersymmetry-breaking masses of right-handed sleptons are unrelated to the other gaugino, slepton and squark masses. Consequently, the lightest neutralino and the right-handed smuon may be light enough to mitigate the discrepancy between the experimental measurement of g(mu) - 2 and the Standard Model calculation, in which case they may be detectable at the LHC and/or a 250 GeV e(+)e(-) collider, whereas the other gauginos and sfermions are heavy enough to escape detection at the LHC.
