Recent development in exploring flavour dynamics in the supersymmetric extension of the Standard Model is reviewed. Emphasis is put on possible interesting effects in b-physics arising for large values of tan beta both in the case of minimal flavour violation and in the case of flavour violation originating in the sfermion sector. The importance of the flavour changing neutral Higgs boson couplings generated by the scalar penguin diagrams and their role in the interplay of neutral B-meson mixing and B^0_{d,s} --> mu^+ mu^- decays is discussed. It is pointed out that observation of the B^0_d --> mu^+ mu^- decay with BR at the level $\simgt 3 X 10^{-8}$ would be a strong indication of nonminimal flavour violation in the quark sector. Possible impact of flavour violation in the slepton sector on neutrino physics is also discussed.
