I will summarize the current knowledge of top quark electroweak couplings. Those couplings are defined through the interaction of a top quark with a photon, Z, W or Higgs boson. Most constraints on these couplings are set by electroweak precision data (LEP/SLC) or by indirect determinations from hadron colliders. The upcoming LHC run will allow, for the first time, to directly probe those couplings in the processes pp --> ttbar+gamma/Z/W/H. I will review the status of theory predictions for these processes and then focus on coupling determinations in pp --> ttbar+Z and ttbar+gamma production at the LHC. Finally, I will discuss projected limits on higher-dimensional operators which arise from physics beyond the SM and lead to deviations from the SM coupling values
