Radiative one-loop corrections to fermion pair production in e+e− annihilation are calculated in the Minimal Supersymmetric Standard Model (MSSM). The size of the non-standard corrections is discussed for the process e^+e^- to mu^+mu^- and e^+e^- to hadrons at LEP2 energies and for e^+e^- to t tbar at a high energy e^+e^- collider. The relative difference between the predictions of the MSSM and the Standard Model is typically below 10%.
