CV surveys with eROSITA

eROSITA will perform the most sensitive X-ray all-sky ever in the energy range 0.3 - 10 keV. It will likely uncover several 10^4 compact binaries, most of them will be cataclysmic variable stars. After a brief introduction to eROSITA we will discuss the source content of the eROSITA surveys, the expected number of CVs and possible strategies for the optical follow-up.
