  We provide evidence for partial deconfinement -- the deconfinement of a
SU($M$) subgroup of the SU($N$) gauge group -- by using lattice Monte Carlo
simulations. We take matrix models as concrete examples. By appropriately
fixing the gauge, we observe that the $M\times M$ submatrices deconfine. This
gives direct evidence for partial deconfinement at strong coupling. We discuss
the applications to QCD and holography.
