We present measurements of the production of top quarks in proton-proton collisions at 7 TeV with the ATLAS detector at the Large Hadron Collider. The cross section of top-quark pair production is measured in the single lepton, dilepton, all hadronic channel and channels with tau leptons. Measurements of single top-quark production in the t-channel is also shown and the single-top quark production in the Wt- and s-channels is explored.
