  Recent searches conducted at the Fermilab Tevatron for the Higgs boson in the
diphoton decay channel are reported using 7.0 fb$^{-1}$ and 8.2 fb$^{-1}$ of
data collected at the CDF and D0 experiments, respectively. Although the
standard model (SM) branching fraction is small, the diphoton final state is
appealing due to better diphoton mass resolution compared with dijet final
states. In addition, other models --- such as fermiophobic models where the
Higgs does not couple to fermions --- predict much larger branching fractions
for the diphoton decay. Here, results are presented for both a SM and
fermiophobic Higgs boson as well as a SM search based on a combination of the
CDF and D0 analyses.
