  These lectures on Higgs boson collider searches were presented at TASI 2006.
I first review the Standard Model searches: what LEP did, prospects for
Tevatron searches, the program planned for LHC, and some of the possibilities
at a future ILC. I then cover in-depth what comes after a candidate discovery
at LHC: the various measurements one has to make to determine exactly what the
Higgs sector is. Finally, I discuss the MSSM extension to the Higgs sector.
