This talk will give an overview of the latest measurements of semileptonic and rare radiative decays of B-mesons at the B-Factories and discuss their relevance for New Physics searches. As radiative B-meson decays proceed through loop diagrams they are sensitive to contributions from particles outside the Standard Model. Semileptonic B-meson decays provide an excellent probe for the weak and strong interactions of the b quark and allow a precision determination of the magnitudes of the Cabibbo-Kobayashi- Maskawa (CKM) matrix elements |V_cb| and |V_ub|. These provide an important test of the Standard Model mechanism for CP violation and the unitarity of the CKM matrix, in particular through the comparison with sin(2beta).
