A precise measurement of the [ital D][sub [ital s]][sup [plus minus]] meson lifetime is reported. The data were accumulated by the high energy photoproduction experiment E687 at Fermilab in the 1990--1991 fixed target run. The measurement has been done using 900 fully reconstructed [ital D][sub [ital s]][sup [plus minus]][r arrow][phi][pi][sup [plus minus]] decays. The lifetime of the [ital D][sub [ital s]][sup [plus minus]] meson is measured to be 0.475[plus minus]0.020[plus minus]0.007 ps.
