### Description

We present the results of radiative and annihilation penguin $B(B_{s})$ decays at Belle. The $b\rightarrow s (d)\gamma$ processes are sensitive to physics beyond the Standard Model as new heavy particles can enter the loop and change the branching fractions and/or the kinematic variables. We report the results of fully inclusive $B\rightarrow X_{s,d}\gamma$ decay with both leptonic tagging and hadronic tagging methods. We also report the results of the exclusive decays $B(B_{s})\rightarrow \phi\gamma$ and $B_{s}\rightarrow \gamma\gamma$.
