  The diphoton excess around 750 GeV observed by ATLAS and CMS can be
interpreted as coming from a massive spin-2 excitation. We explore this
possibility in the context of warped five-dimensional models with the Standard
Model (SM) fields propagating in the bulk of the extra dimension. The 750 GeV
resonance is identified with the first Kaluza-Klein (KK) excitation of the
five-dimensional graviton that is parametrically lighter than KK resonances of
SM fields. Our set-up makes it possible to realize non-universal couplings of
the spin-2 resonance to matter, and thus to explain non-observation of the 750
GeV resonance in leptonic channels. Phenomenological predictions of the model
depend on the localization of fields in the extra dimension. If, as required by
naturalness arguments, the zero modes of the Higgs and top fields are localized
near the IR brane, one expects large branching fractions to ttbar, hh, WW, and
ZZ final states. Decays to a Z boson and a photon can also be observable when
the KK graviton couplings to the SM gauge fields are non-universal.
