Measurements of the top quark mass in proton-proton collisions at the LHC at √s = 7TeV are presented from data collected by the CMS and ATLAS experiments. The t¯t samples are reconstructed in the lepton+jet final state, where events are required to have exactly one isolated electron or muon and at least four jets, and in the dilepton final state, with two leptons, at least two jets, and missing transverse energy. The different methods used for the top quark measurement are described. The indirect top quark mass determination from the cross section and the measurement of the top-antitop quark mass difference are also presented.
