XEUS (X-ray Evolving Universe Spectroscopy) was a space observatory plan developed by the European Space Agency (ESA) as a successor to the successful XMM-Newton X-ray satellite telescope. It was merged to the International X-ray Observatory (IXO) around 2008, but as that project ran into issues in 2011, the ESA component was forked off into Advanced Telescope for High Energy Astrophysics (Athena).

XEUS consisted of a mirror spacecraft that carried a large X-ray telescope, with a mirror area of about 5 m² and an imaging resolution better than 5 arcsec; for X-ray radiation with an energy of 1 keV. A detector spacecraft would have flown in formation with the telescope at a distance of approximately 50 m, in the focus of the telescope. The detectors would have included a wide-field X-ray imager with an energy resolution of 150 eV at 6 keV, as well as a cryogenic narrow-field imager with an energy resolution of 2 eV at 1 keV.
