The production of pairs of charged Higgs bosons as predicted by the minimal
supersymmetric standard model (MSSM) via the gluon fusion mechanism is inv
estigated. The amplitudes at the leading one-loop order for the parton proc
ess gg --> H+H- are calculated with the complete set of MSSM particles. Num
erical results are presented for the cross section of the inclusive hadron
process pp --> gg --> H+H- + X at the LHC.
