We cross-matched the 4XMM-DR10 catalog with the HyperLEDA database and obtained a new sample of galaxies that contain X-ray sources. Excluding duplicate observations and false matches, we present a total of 7759 galaxies with X-ray sources. In the current work, we present general properties of the sample: namely the distribution in equatorial coordinates, radial velocity distribution, morphological type, and X-ray fluxes. The sample includes morphological classification for 5241 galaxies with X-ray emission, almost half of which, $42\%$, are elliptical (E, E-S0). Most galaxies in the sample have nuclear X-ray emission (6313 or 81$\%$), and the remaining 1443 (19$\%$) present X-ray emission from the host galaxy. This sample can be used for future deep studies of multi-wavelengths properties of the galaxies with X-ray emission.
