We report the serendipitous discovery of a broad absorption line (BAL) QSO at z = 2.169, located 41" southwest of 3C 48. We present Keck Low Resolution Imaging Spectrometer spectroscopy covering rest-frame wavelengths 1500-2300 Å. The C IV BAL has three components, and it extends to outflow velocities of at least 12,000 km.s^–1. The BAL QSO has an intervening low-ionization metal-line absorption system at z = 1.667, which is likely to be a damped Lyα absorber. Hubble Space Telescope images show extended luminous material around the QSO, which could be either the host galaxy or the intervening system.
