  We demonstrate that the South Pole kilometer-scale neutrino observatory
IceCube can detect multi-TeV gamma rays continuously over a large fraction of
the southern sky. While not as sensitive as pointing atmospheric Cerenkov
telescopes, IceCube can roughly match the sensitivity of Milagro. Also, IceCube
is complementary to Milagro because it will observe, without interruption, a
relatively poorly studied fraction of the southern sky. The information which
IceCube must record to function as a gamma ray observatory is only the
directions and possibly energies of down-going muons.
