Using 20.2 ks of Swift X-Ray Telescope (XRT) observations of the Type IIn SN 2010jl in UGC 5189A (CBET #2532, 2536), obtained between 2010-11-05.04 and 2010-11-05.78, an X-ray point-source is detected, consistent with the optical position of the SN, with a 6.5-sigma significance of source detection. The PSF, dead-time, and vignetting corrected XRT net count rate is (2.8+/-0.4)E-03 cts/s, corresponding to an unabsorbed (0.2-10 keV band) X-ray flux of (1.3+/-0.2)E-13 erg/cm/cm/s and a luminosity of (3.6+/-0.5)E40 erg/s for an adopted thermal plasma spectrum with a temperature of kT = 10 keV, a Galactic foreground column density of N_H = 3.03E+20 (Dickey & Lockman, 1990, ARAA 28) and a distance of 48 Mpc (NED).
