We construct intersecting brane configurations in anit-de Sitter (AdS) space which localize gravity to the intersection region, generalizing the trapping of gravity to any number n of infinite extra dimensions. Since the 4D Planck scale MPl is determined by the fundamental Planck scale M* and the AdS radius L via the familiar relation M2Pl~M2+n*Ln, we get two kinds of theories with TeV scale quantum gravity and submillimeter deviations from Newton's law. With M*~TeV and L~submillimeter, we recover the phenomenology of theories with large extra dimensions. Alternatively, if M*~L-1~MPl, and our 3-brane is at a distance of ~100M-1Pl from the intersection, we obtain a theory with an exponential determination of the weak/Planck hierarchy.
