Abstract
Gamma-ray binaries are a subclass of high-mass binary systems whose energy spectrum peaks at high energies (HE, E>100 MeV) and extends to very high energies (VHE, E>100 GeV) gamma-rays. In this review we summarize properties of well-studied non-transient gamma-ray binaries as well as briefly discuss poorly known systems and transient systems hosting a microquasar. We also discuss theoretical models that have been used to describe spectral and timing characteristics of considered systems.
