We present precision measurements of the D0 and D+ meson lifetimes using approximately 7500 fully reconstructed D0→K-π+, K-π+π+π-, D+→K-π+π+, and charge conjugate decays. The data were accumulated by the Fermilab high ene rgy photoproduction experiment E687. The lifetime of the D0 is measured to be 0.424±0.011±0.007 ps while the D+ lifetime is measured to be 1.075±0.040±0.018 ps.
