  In these lectures I briefly review the Higgs mechanism of electroweak
symmetry breaking and focus on the most relevant aspects of the phenomenology
of the Standard Model Higgs boson at hadron colliders, namely the Tevatron and
the Large Hadron Collider. Emphasis is put in particular on the Higgs-physics
program of both LHC experiments and on the theoretical activity that has
entailed from the the need of providing accurate predictions for both signal
and background in Higgs-boson searches.
