abstract
Many searches for additional Higgs bosons, which are predicted by a lot of interesting models beyond the standard model, have been performed at the LHC. Some selected latest results of the searches for extra Higgs bosons at the LHC are presented. These additional Higgs bosons could be produced either directly from the parton interactions or from the decays of the observed standard model Higgs boson or a new heavier resonance. The searches used the data from proton-proton collisions delivered by the LHC at a centre-of-mass energy of $\sqrt{s}=13~\TeV$ and recorded with the ATLAS and CMS detectors. No direct evidence of new physics has been observed yet. Several mild excesses were observed in some final states. More data is needed to conclude on the nature of these excesses.
