  In the general scenario of Weakly Interacting Massive Particles (WIMP), dark
matter (DM) can be observed via astrophysical gamma rays because photons are
produced in various DM annihilation or decay processes, either as broad-band or
line emission, or because of the secondary processes of charged particles in
the final stages of the annihilations or the decays. The energy range of the
former processes is accessible by current ground-based Imaging Atmospheric
Cherenkov telescopes (IACTs, like H.E.S.S., MAGIC and VERITAS). The strengths
of this technique are: a) the expected DM gamma-ray spectra show peculiar
features like bumps, spikes and cutoff that make them clearly distinguishable
from the smoother astrophysical spectra, b) the expected DM spectrum is
universal and therefore by observing two or more DM targets with the same
spectrum, a clear identification (besides detection) of DM would be enabled.
The role of IACTs may gain more importance in the future as the results from
the LHC may hint to a DM particle with mass at the TeV or above, where the
IACTs sensitivity is unsurpassed by other experiments. In this contribution, a
review of the search for DM with the current generation of IACT will be
presented.
