Observation of $t\bar{t}H$ production with ATLAS

An overview of the analyses that led to the observation of the Higgs boson production in association with a top quark pair ($t\bar{t}H$) with the ATLAS experiment is given. Up to 80 fb${}^{-1}$ of proton-proton collision data recorded by the ATLAS experiment at a center-of-mass energy of $\sqrt{s}=13$ TeV at the Large Hadron Collider (LHC) have been used to achieve this major milestone.
