Abstract:	The correlation between black hole mass MBH and the central stellar velocity dispersion σ in nearby elliptical galaxies affords a novel way to determine MBH in active galaxies. We report on measurements of σ from optical spectra of 7 BL Lac host galaxies. The range of σ (160 - 290 km s-1) corresponds to estimated MBH of 5 × 107 - 9 × 108 solar masses. The average ratio of MBH to the host galaxy mass is 1.4 × 10-3, consistent with that estimated in other active and inactive galaxies. The range of σ and MBH of the BL Lacs are similar to those obtained for low redshift radio galaxies, in good agreement with the predictions of the unified models for radio-loud active galaxies.
