Chandra observation of PSR B1823-13 show a point source within 0.5 arcsec of the pulsar's radio position, which we identify as the pulsar's X-ray counterpart. The background subtracted flux of the point source in the 0.4--5 keV band is 4.2 counts ks-1. The point source is surrounded by a PWN extending about 5 arcsec from the point source. The PWN shows a hard spectrum with a photon index of approximately 1. The PWN has an average surface brightness of approximately 0.18 counts ks-1 arcsec-2. We find a point-like source about 8.2 arcsec away from the pulsar which appears to be aligned with a filament extending outwards from the PWN.
