  A review of the charmed meson and baryon lifetimes is presented. Our
knowledge of charmed particle lifetimes has greatly improved over the past two
years, a crucial r\^ole having been played by the E687 experiment at Fermilab,
which has almost quadrupled the samples of $D$ mesons. The lifetime ratios
$\tau(D^+)/\tau(D^0)$ and $\tau(D_s^+)/\tau(D^0)$ are now known with an
accuracy of 1.7\% and 3.7\% respectively. In the baryon sector the statistics
is still limited, but the experimental results on $\Lambda_c^+$, $\Xi_c^0$ and
$\Xi_c^+$ exhibit a clear pattern of lifetime hierarchy, as expected from
simple theoretical arguments. The first measurement of $\tau(\Omega_c^0)$ from
E687 is also presented to complete the charmed baryon lifetime picture. The
more accurate experimental scenario can provide information on non-perturbative
QCD effects and the hadronic matrix elements.
