We explore the possibility of generalizing the locally localized gravity model in five space-time dimensions to arbitrary higher dimensions. In a space-time with a negative cosmological constant, there are essentially two kinds of higher-dimensional cousins which not only take an analytic form but also are free from the naked curvature singularity in a whole bulk space-time. One cousin is a trivial extension of five-dimensional model, while the other one is in essence in higher dimensions. One interesting observation is that in the latter model, only the anti--de Sitter (AdSp) brane is physically meaningful, whereas de Sitter (dSp) and Minkowski (Mp) branes are dismissed. Moreover, for the AdSp brane in the latter model, we study the property of localization of various bulk fields on a single brane. In particular, it is shown that the presence of the brane cosmological constant enables a bulk gauge field and massless fermions to confine to the brane only by a gravitational interaction. We find a novel relation between the mass of the brane gauge field and the brane cosmological constant.
