In preparation for the upcoming all-sky data releases of the Gaia mission, we compiled a catalog of known hot subdwarf stars and candidates drawn from a variety of sources. This catalog is intended to provide a comprehensive overview of the properties of these stars, including their spectral types, luminosities, and locations in the sky. The catalog will be a valuable resource for astronomers and astrophysicists seeking to understand the properties and behavior of hot subdwarf stars, and will provide a foundation for future research into these enigmatic objects.
