ATLAS results on exotic hadronic resonances

Recent results from the proton-proton collision data taken by the ATLAS experiment on exotic resonances will be presented. A search for $J/\psi p$ resonances in $\lambda_{b}\rightarrow J/\psi p K$ decays with large $p K$ invariant masses will be reported. Studies of $Z_{c}$ states in $B$-meson decays with the Run 2 data at 13 TeV will also be discussed. Searches for exotic resonances in 4 muon final states will be shown.
