Measurements of the top quark mass in proton-proton collisions with the ATLAS detector at the Large Hadron Collider are presented. They are performed in various channels: single lepton, dilepton and all-hadronic final states. The most precise measurement is obtained in the single lepton channel using a 3-dimensional template technique which determines the top quark mass together with a global jet energy scale factor, and a relative b-jet to light-jet energy scale factor.
