Over the next decade hadron colliders will play an important role in the investigation of fundamental questions of particle physics. The high collision energy of the Fermilab  Tevatron p\bar p collider and the CERN  Large Hadron Collider (LHC) will allow to probe physics in a new energy domain. In addition, important precision measurements in the area of electroweak physics can be carried out. In particular the experiments at the LHC have a large potential to explore physics beyond the Standard Model and to investigate the nature of electroweak symmetry breaking. In the present article the physics potential of the Tevatron and the LHC is summarized.
