A strong X-ray source only 8 \arcsec from the nucleus of the Seyfert 2 galaxy NGC 7319 in Stephan's Quintet has been discovered by Chandra. We have identified the optical counterpart and observed its spectrum with the Keck I 10-m telescope. It is a QSO with z_e = 2.114. It is also a ULX with L_x = 1.5 x 10⁴⁰ erg sec^-1. Our Keck spectra show that it is very likely that the QSO is interacting with the interstellar gas in NGC 7319.
