  We present results of a Chandra observation of a field in NGC 2264. The
observations were taken with the ACIS-I camera with an exposure time of 48.1
ks. We present a catalog of 263 sources, which includes X-ray luminosity,
optical and infrared photometry and X-ray variability information. We found 41
variable sources, 14 of which have a flare-like light curve, and 2 of which
have a pattern of a steady increase or decrease over a 10 hour period. The
optical and infrared photometry for the stars identified as X-ray sources are
consistent with most of these objects being pre-main sequence stars with ages
younger than 3 Myr.
