The renormalization group running of a seesaw mass matrix for the neutrinos in the Standard Model, a class of Two Higgs Models and in the Minimal Supersymmetric Standard Model is studied. A formalism for calculating ß-functions for tensorial quantities in MS-like renormalizations schemes is presented. The corresponding Renormalization Group Equations for all three models are derived. Moreover, a general method of checking ß-functions of effective theories is presented and applied in an example. Furthermore, a "construction kit" for computing ß-functions of renormalizable and non-renormalizable operators in general N=1 supersymmetric theories is derived. Finally, the effects of non-degenerate see-saw scales on the renormalization group evolution of mixing angles are investigated.
