The two-loop QCD corrections to the ρ parameter are derived in the Minimal Supersymmetric Standard Model. They turn out to be sizable and modify the one-loop result by up to 30%. Furthermore exact results for the gluonic corrections to Δr are presented and compared with the leading contribution entering via the ρ parameter.
