Intermediate-mass black holes (IMBHs) with masses between those of
``stellar-mass'' and ``supermassive'' black holes (BHs) might have
formed in the Universe in several different ways. I review the
constraints that dynamical considerations and gravitational lensing
observations place on both the existence of IBMHs and their possible
contribution to the cosmological mass density. IMBH formation theories
(Miller) and constraints from X-ray observations (Mushotzky) are
reviewed elsewhere in this volume. IMBHs are of potential importance
for several fields of astrophysics, and are potential sources for
gravitational wave detection. As such, they are likely to grow as a
focus of research attention.
