I present results for top quark production in hadronic collisions at LHC andTevatron energies. The soft-gluon corrections to the differential cross sectionare resummed at next-to-next-to-leading-logarithm (NNLL) accuracy via thetwo-loop soft anomalous dimension matrices. Approximatenext-to-next-to-leading-order (NNLO) differential and total cross sections arecalculated. Detailed theoretical predictions are shown for the t tbar crosssection and the top quark p_T distribution at the Tevatron and the LHC.
