  Microquasars are X-ray binary stars with the capability to generate
relativisticjets. It is expected that microquasars are gamma-ray sources,
because of the analogy with quasars and because the theoretical models predict
emission at such energy range. In addition, from observational arguments, there
are two microquasars that appear as the possible counterparts for two
unidentified high-energy gamma-ray sources.
