We study the two-loop renormalization group equation for the running gaugino mass in the supersymmetric gauge theory. We find that both in the MS and DR renormalization schemes, the well-known proportionality of the runnings of the gaugino mass and the gauge coupling constant is violated at the two-loop order, even in models with vector supermultiplets only. The scheme dependence of the running gaugino mass is clarified.
