A precise measurement of the Ds± 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 Ds±→φπ± decays. The lifetime of the Ds± meson is measured to be 0.475±0.020±0.007 ps.
