Abstract: We report on recent measurements of hadronic $B$ decays using the data set collected from 2019 to 2021 by the Belle~II experiment and corresponding to an integrated luminosity of 189.8 ${\rm fb^{-1}}$. We present the measurement of the CKM angle $\gamma$, performed combining Belle~II data with the full Belle data set, and measurements of $B^0-\bar{B}^0$ mixing frequency and $B^0$ lifetime, branching fractions and ${\it CP}$-violating asymmetries of $B^+ \to \rho^+\rho^0$ and $B^0 \to K_S^0\pi^0$ decays.
