Sumario:Measurements of the top quark production cross sections in proton-proton collisions with the ATLAS detector at the Large Hadron Collider are presented. The measurement require either no, one or two leptons (electrons or muons) in the final state (single lepton, dilepton, hadronic channel). The main focus of this paper are measurements of differential spectra of $tar{t}$ final states, in particular, measurements that are able to constrain the modelling of additional parton radiation. We also discuss the production of top quark pairs in association with heavy quarks (beauty and charm). Measurements of single top-quark production in the $t$- and $Wt$-channels are presented and determination of the CKM matrix element $|V_{tb}|$ is also discussed.
