The search for the Standard Model Higgs boson at present and future colliders

I briefly review the Higgs sector in the Standard Model. After summarizing the properties of the Higgs boson, I will discuss the prospects for discovering this particle at the present colliders LEP2 and Tevatron and at the next generation colliders LHC and a high-energy $e^+e^-$ linear collider. The possibilities of studying the properties of the Higgs particle will be then summarized.
