Abstract	We report on absolute lifetime measurements of charmed hadrons using the data collected by the Belle II experiment between 2019 and 2021. The measured lifetimes of $D^0$, $D^+$, and $\Lambda_c^+$ are the most precise to date and consistent with previous measurements. Our result indicates that $\Omega_c^0$ is not the shortest-lived singly charmed baryon.
