The ATLAS detector at CERN is a multi-purpose experiment that had its most notable accomplishment with the discovery of the Higgs boson in 2012. While this particle completes the Standard Model, there are still many open questions, calling for new physics beyond the Standard Model. Many such models include an extended Higgs sector and thus predict the presence of additional neutral or charged scalars.
This talk reports on the latest BSM Higgs results from ATLAS using the full LHC run-2 dataset of proton-proton collisions. Small excesses will be highlighted, and some comparisons with results from the CMS experiment will be made. The constraints on parameters in various BSM models will also be discussed.
