  These lectures start with a detailed pedagogical introduction to electroweak
symmetry breaking in the Standard Model, including gauge boson and fermion mass
generation and the resulting predictions for Higgs boson interactions. I then
survey Higgs boson decays and production mechanisms at hadron and $e^+e^-$
colliders. I finish with two case studies of Higgs physics beyond the Standard
Model: two-Higgs-doublet models, which I use to illustrate the concept of
minimal flavor violation, and models with isospin-triplet scalar(s), which I
use to illustrate the concept of custodial symmetry.
