The authors present a complete X-ray image of the supernova remnant PKS 1209-52 obtained with the Einstein Observatory. The remnant appears as a heavily fragmented shell at X-ray wavelengths. The X-ray morphology is similar to that at radio wavelengths, while a compact X-ray source is clearly detected near the center. The flux from the point like X-ray source is ≡4×10-12ergs cm-2s-1 between 0.1 and 4 keV. No viable optical counterparts down to V ≡ 19 have been found in the 3arcsec.3 radius error circle determined by the High Resolution Imager. The point X-ray source is most likely either a hot neutron star or a synchrotron-emitting pulsar resulting from the supernova explosion.
