We present a catalog of 5184 candidate infrared counterparts to X-ray sourcesdetected towards the Galactic center. The X-ray sample contains 9017 pointsources detected in this region by the Chandra X-ray Observatory, includingdata from a recent deep survey of the central 2 x 0.8 deg of the Galacticplane. A total of 6760 of these sources have hard X-ray colors, and themajority of them lie near the Galactic center, while most of the remaining 2257soft X-ray sources lie in the foreground. We cross-correlated the X-ray sourcepositions with the 2MASS and SIRIUS near-infrared catalogs, which collectivelycontain stars with a 10-sigma limiting flux of K_s<=15.6 mag. In order todistinguish absorbed infrared sources near the Galactic center from those inthe foreground, we defined red and blue sources as those which have H-K_s>=0.9and <=0.9 mag, respectively. We find that 5.8(1.5)% of the hard X-ray sourceshave real infrared counterparts, of which 228(99) are red and 166(27) are blue.The red counterparts are probably comprised of WR/O stars, HMXBs, andsymbiotics near the Galactic center. We also find that 39.4(1.0)% of the softX-ray sources have blue infrared counterparts; most of these are probablycoronally active dwarfs in the foreground. There is a noteworthy collection of~20 red counterparts to hard X-ray sources near the Sagittarius-B H II region,which are probably massive binaries that have formed within the last severalMyr. For each of the infrared matches to X-ray sources in our catalog wederived the probability that the association is real, based on the results ofthe cross-correlation analysis. The catalog will serve spectroscopic surveys toidentify infrared counterparts to X-ray sources near the Galactic center.
