  This is a pedagogical introduction into theories with branes and extra
dimensions. We first discuss the construction of such models from an effective
field theory point of view, and then discuss large extra dimensions and some of
their phenomenological consequences. Various possible phenomena (split
fermions, mediation of supersymmetry breaking and orbifold breaking of
symmetries) are discussed next. The second half of this review is entirely
devoted to warped extra dimensions, including the construction of the
Randall-Sundrum solution, intersecting branes, radius stabilization, KK
phenomenology and bulk gauge bosons.
