We construct intersecting brane configurations in anitde 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 M{sub Pl} is determined by the fundamental Planck scale M{sub *} and the AdS radius L via the familiar relation M{sup 2}{sub Pl}{approx}M{sup 2+n}{sub *}L{sup n} , we get two kinds of theories with TeV scale quantum gravity and submillimeter deviations from Newton's law. With M{sub *}{approx}TeV and L{approx}submillimeter , we recover the phenomenology of theories with large extra dimensions. Alternatively, if M{sub *}{approx}L{sup -1}{approx}M{sub Pl} , and our 3-brane is at a distance of {approx}100M{sup -1}{sub Pl} from the intersection, we obtain a theory with an exponential determination of the weak/Planck hierarchy.
