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 pair-produced top quarks is measured in several channels, including the single lepton, dilepton and all hadronic channel, some using information from b-tagging.
