In these lectures I discuss the range of models which have been proposed to explain electroweak symmetry breaking. I begin with an overview of Higgs models, with emphasis on the naturalness/hierarchy and triviality problems, and then consider general lessons which can be drawn about the symmetry breaking sector in arbitrary scalar models. Subsequently, I discuss the symmetry breaking sector in supersymmetric models and then consider models of dynamical electroweak symmetry breaking. I conclude with a brief review of the open questions.73 pages, 74 figures.
