Abstract	An overview of the search for $Z\gamma$ resonances using proton-proton collision data recorded by the ATLAS detector is presented. A search for evidence of a Standard Model Higgs boson undergoing the decay $H \rightarrow Z\gamma, Z\rightarrow\ell\ell$, where $\ell = e$ or $\mu$, has been performed, and a brief summary of the most recent public results is given. A search for exotic high mass resonances decaying to a $Z\gamma$ final state has been performed using proton-proton collision data recorded at $\sqrt{s} = 13$ TeV. Leptonic decays of the $Z$ boson ($Z\rightarrow\ell\ell$, where $\ell = e$ or $\mu$) have been investigated, together with hadronic decay modes ($Z\rightarrow q\bar{q}$). An overview of the most recent public results is presented.
