We compute the exact two-loop matching coefficient for the bottom-quark mass m{sub b}, within the Minimal Supersymmetric Standard Model (MSSM), taking into account O({alpha}{sub s}{sup 2}) contributions from the Supersymmetric Quantum Chromodynamics (SQCD). We find that the three-loop order corrections to the running bottom-quark mass exceed the uncertainty due to the current experimental accuracy. They can reach up to 30% from the tree-level m{sub b}, for models with large values of tan {beta} and relatively light SUSY mass scale.
