  The top-quark mass is one of the fundamental parameters of the Standard Model
of particle physics. The latest ATLAS measurements of the top-quark mass in top
quark pair final states are presented. Measurements use di-lepton, lepton+jets
and all-jets final states and their combination is performed. Measurements of
the top-quark pole mass based on precision theoretical QCD calculations for
lepton kinematic distribution and for top quark pair production with an
additional jet are also presented.
