Using a sample of 9.6×106BB̅ meson pairs collected with the CLEO detector, we have fully reconstructed 135 B0→ψ(′)KS0 and 526 B+→ψ(′)K+ candidates with very low background. We fitted the ψ(′)K invariant mass distributions of these B meson candidates and measured the masses of the neutral and charged B mesons to be M(B0)=5279.1±0.7[stat]±0.3[ syst]MeV/c2 and M(B+)=5279.1±0.4[stat]±0.4[ syst]MeV/c2. The precision is a significant improvement over previous measurements.
