Higgs Boson Searches at the Tevatron

The Tevatron experiments are currently the world's most sensitive experiments for searching for the Higgs boson. They are sensitive enough to find evidence of the Standard Model Higgs boson, if it has a large mass, and are nearly sensitive enough to find evidence at lower mass or to exclude the Standard Model Higgs boson at all masses, if it does not exist. This review describes the recent experimental progress achieved at the Tevatron at a time when the discovery of the Higgs boson is considered imminent.
