  INTEGRAL is an ESA mission in fundamental astrophysics that was launched in
October 2002. It has been in orbit for over 18 years, during which it has been
observing the high-energy sky with a set of instruments specifically designed
to probe the emission from hard X-ray and soft gamma-ray sources. This paper is
devoted to the subject of black hole binaries, which are among the most
important sources that populate the high-energy sky. We present a review of the
scientific literature based on INTEGRAL data, which has significantly advanced
our knowledge in the field of relativistic astrophysics. We briefly summarise
the state-of-the-art of the study of black hole binaries, with a particular
focus on the topics closer to the INTEGRAL science. We then give an overview of
the results obtained by INTEGRAL and by other observatories on a number of
sources of importance in the field. Finally, we review the main results
obtained over the past 18 years on all the black hole binaries that INTEGRAL
has observed. We conclude with a summary of the main contributions of INTEGRAL
to the field, and on the future perspectives.
