The LSST will provide great advances in our understanding of the demography and physics of AGNs, owing to its unprecedented combination of solid-angle coverage, photometric and astrometric accuracy, sensitivity, broad wavelength coverage, and time sampling. Well-defined, large (> 107 objects) samples of AGNs at 0 < z < 7 can be constructed via four approaches: location in color-color space, variability, lack of proper motion, and matching to multiwavelength data. The samples will allow studies of the AGN luminosity function and AGN clustering down to Seyfert luminosities out to z 6-7. The time baseline (hours to years), coupled with the large sample size, will produce a data set that can be used to address the physics of the AGN accretion process, allowing insights into the fueling of AGNs by stellar tidal disruptions and the lifetime of AGNs. Comparison of LSST data with archival X-ray and infrared fields will be the first stage of follow-up for hundreds of thousands of AGNs, many of which will be heavily obscured.
