Searches for Beyond Standard Model Higgs Bosons with ATLAS

The search for evidence of beyond Standard Model Higgs Bosons is an integral part of the Higgs bosons studies at the LHC. This article reviews recent beyond Standard Model Higgs searches using 2--5 fb$^{-1}$ of 7 TeV LHC proton-proton collision data recorded by the ATLAS detector. No significant deviations from the background expectations are found and corresponding constraints on physics beyond the Standard Model are obtained.
