We present the measurements of the leptonic asymmetries in Z0 decays measured by the SLD experiment at SLAC. A data sample of approximately 550,000 Z0 bosons are used for the preliminary measurement of ALR(Ae) and the leptonic final state measurements of Ae, Aμ and Aτ, representing the entire set of 1992-1998 SLD runs. When combining all results, a preliminary value for the effective weak mixing angle is obtained: sin2θWeff = 0.23109 ± 0.00029. We also present the direct measurements of Ab from left-right forward-backward asymmetries, using partial data samples from 1993-1998 SLD runs. The preliminary value combines jet charge, cascade kaon and semileptonic decay analyses to obtain Ab = 0.866 ± 0.036.
