Abstract: We give a brief introduction to theories with extra dimensions. We firstintroduce the basic formalism for studying extra-dimensional theories,including the Kaluza-Klein decomposition and the effective theory for 3-branes.We then focus on two types of scenarios: large extra dimensions as a solutionto the hierarchy problem and TeV$^{-1}$-size extra dimensions with StandardModel fields propagating in them. We discuss the experimental tests andconstraints on these scenarios, and also the questions in particle physicswhich may be addressed with the help of extra dimensions. This is the write-upof the lectures given at the 2009 TASI summer school. Other interesting topicssuch as warped extra dimensions are covered by other lecturers.
