A measurement of the lifetime of the charmed strange baryon [Xi][sub [ital c]][sup 0] is presented. The data were accumulated by the Fermilab high energy photoproduction experiment E687. The measurement has been made using 42[plus minus]10 [Xi][sub [ital c]][sup 0][r arrow][Xi][sup [minus]][pi][sup +] decays. The lifetime of the [Xi][sub [ital c]][sup 0] is measured to be 0.101[sub [minus]0.017][sup +0.025][plus minus]0.005 ps and its mass is measured to be 2462.1[plus minus]3.1[plus minus]1.4 MeV/[ital c][sup 2].
