Sumario:Measurements of the inclusive top quark production cross sections in proton-proton collisions with the ATLAS and CMS detectors at the Large Hadron Collider are presented. The measurements of the precise pair production cross section are performed for di-lepton, semi-leptonic and hadronic final states. Differential measurements of the top transverse momentum and kinematic properties of the top-anti-top pair are also discussed. The results, unfolded to particle and parton level, are compared to recent Monte Carlo generators implementing LO and NLO matrix elements matched with parton showers and NLO QCD calculations. For single top-quark productions cross sections are measured for t-channel, s-channel and W-boson associated production processes. The single top-quark and anti-top total production cross sections, their ratio, as well as a measurement of the inclusive production cross section is presented. All measurements are compared to theoretical calculations and the CKM matrix element |Vtb| is determined.
