| Abstract | We report on the recent measurements of electroweak and radiative penguin $B$~decays at the Belle~II experiment. We use samples of electron-positron collisions collected at the $\Upsilon(4S)$~resonance. We present the measurement of the branching fractions of $B^{+/0}\to K^*(892)^{+/0}\ell^+\ell^-~(\ell=e, \mu)$, $B^{+/0}\to K^{+/0}J/\psi$, and $B^{+/0}\to X_s\gamma$ decays in the data corresponding to 189~fb$^{-1}$ of integrated luminosity. We also present a search of $B^+\to K^+\nu\bar\nu$ decay in the data corresponding to 63~fb$^{-1}$ of integrated luminosity. |
