We present a complete next-to-leading order calculation for the total cross section for inclusive Higgs pair production via bottom-quark fusion at the CERN Large Hadron Collider in the minimal supersymmetric standard model and the minimal supergravity model. We emphasize the contributions of s quark and gluino loops and the decoupling properties of our results for heavy s quark and gluino masses. The enhanced couplings of the b quark to the Higgs bosons in supersymmetric models with large tan{beta} yield large next-to-leading order supersymmetry QCD corrections in some regions of parameter space.
