We have measured the B hadron energy distribution in Z(0) decays using a sample of semileptonic B decays recorded in the SLD experiment at SLAG. The energy of each tagged B hadron was reconstructed using information from the lepton and a partially reconstructed charm-decay vertex. We compared the scaled energy distribution with several models of heavy quark fragmentation. The average scaled energy of primary B hadrons was found to be (x(EB))=0.716+/-0.011(stat)(-0.022)(+0.021)(syst).
