  A generic prediction of scenarios with extra dimensions accessible in
TeV-scale collisions is the existence of Kaluza-Klein excitations of the
graviton. For a broad class of strongly-warped scenarios one expects to
initially find an isolated resonance, whose phenomenology in the simplest cases
is described by a simplified model with two parameters, its mass, and a
constant $\Lambda$ with units of mass parameterizing its coupling to the
Standard Model stress tensor. These parameters are in turn determined by the
geometrical configuration of the warped compactification. We explore the
possibility that the 750 GeV excess recently seen in 13 TeV data at ATLAS and
CMS could be such a warped Kaluza-Klein graviton, and find a best-fit value
$\Lambda\approx 60$ TeV. We find that while there is some tension between this
interpretation and data from 8 TeV and from the dilepton channel at 13 TeV, it
is not strongly excluded. However, in the simplest scenarios of this kind, such
a signal should soon become apparent in both diphoton and dilepton channels.
