  We numerically construct a family of five-dimensional black holes exhibiting
a line of first-order phase transitions terminating at a critical point at
finite chemical potential and temperature. These black holes are constructed so
that the equation of state and baryon susceptibilities approximately match QCD
lattice data at vanishing chemical potential. The critical endpoint in the
particular model we consider has temperature 143 MeV and chemical potential 783
MeV. Critical exponents are calculated, with results that are consistent with
mean-field scaling relations.
