We present newly classified X-ray emitting symbiotic stars detected in the eROSITA all-sky survey. We have analysed the data of four eRASS surveys (eRASS1-4) individually as well as the combined eRASS1:4 dataset. The classification was performed using extensive multi-wavelength studies of optical, infrared, and UV counterparts of the X-ray sources. X-ray spectral and timing analyses have provided a deeper understanding of the accretion/wind collision properties of these newly classified X-ray emitting symbiotic stars, opening a window to further studies of individual sources and population studies.
