Top quark production

We review the current status of the cross sections measurement of the top-quark at the LHC and at the Tevatron. Total production cross sections, studies using single top quark events and differential $\rm{t}\bar{\rm t}$ cross sections are discussed. The associated production of top quark pairs with photons, Z and W bosons, including $\rm{t}\bar{\rm t}$Z and $\rm{t}\bar{\rm t}$W measurements shown for the first time at LHCP2014, are presented.
