Abstract. The dwarf galaxy NGC~300 has been studied twice with the EPIC instruments on board XMM-Newton for a total net observing time of 66 ksec. In the energy range 0.3 to 6 keV a total of 167 sources were detected with the pn-CCD camera above a likelihood level of 10 (corresponding to 4 sigma). 86 of these sources are found within or close to the D₂₅ confine (22'×15') of the galaxy. We compare the global properties of these sources with a subset of 26 sources already discovered by ROSAT. The brightest object in the galaxy, a Black Hole X-ray binary candidate, is found to vary by more than a factor of 20.

Key words: galaxies: individual (NGC 300) - X-rays: galaxies
