  The minimal supergravity model (SUGRA), with gauge coupling unification and
radiative electroweak symmetry breaking, is a well-motivated paradigm for
physics Beyond the Standard Model. In this talk, I review the capabilities of
various present and future collider experiments to make definitive tests of the
SUGRA model, including LEP and LEP II, the Tevatron and its upgrades, and
finally the CERN LHC project.
