We report a measurement of the $D^0$ and $D^+$ lifetimes using $D^0$���$K^-��^+$ and $D^+$���$K^-��^+��^+$ decays reconstructed in $e^+e^-$��� $c\overline{c}$ data recorded by the Belle II experiment at the SuperKEKB asymmetric-energy $e^+e^-$ collider. The data, collected at center-of-mass energies at or near the $��$(4S) resonance, correspond to an integrated luminosity of 72 fb$^{-1}$. The results, $��$($D^0$)=410.5��1.1(stat)��0.8(syst) fs and ��($D^+$)=1030.4��4.7(stat)��3.1(syst) fs, are the most precise to date and are consistent with previous determinations.
