Abstract: We have used the Two Micron All Sky Survey (2MASS) to produce a large (>4000) sample of Seyfert galaxies and quasars which overcomes the incompleteness of previous searches imposed by extinction. Half of the candidates were found by requiring that the central (H – K) color of XSC sources was greater than 0.6. An equal number of AGN candidates, at higher redshifts, was obtained from PSC sources with total (H – K) colors greater than 0.6. Over the entire sky more than 20 degrees away from the galactic plane, the resulting 2MASS Bright Seyfert sample is complete down to a nonstellar nuclear flux limit of KAGN = 13.5, except for Seyfert nuclei which are fainter than starlight within the central seeing disk. Less than half of the sample has been detected in the ROSAT All Sky Survey.
