Imaging polarimetry of the Beta Pic disk shows that it is reflection nebulosity solely illuminated by the central star. The level of polarization in both segments of the disk is 17 + or - 3 percent (R waveband) and is relatively constant in the distance range 15-30 arcsec from the star. It is found that the Beta Pic disk shows up in polarized light when the light surrounding the bright star is treated as simple reflection nebulosity. This procedure does not require complicated background subtractions from reference stars and should provide a simple and fast method of locating planetary and protoplanetary disks surrounding other stars.
