  Generic extensions of the Standard Model that respect baryon and lepton
numbers have accidentally stable particles. Typical examples are the lightest
exotic neutral fermion, or "neutralino", and fields with non-trivial lepton and
baryon charges. In this paper we show that an accidentally stable neutralino is
a natural dark matter candidate in models with warped extra dimensions. We find
that annihilation into other Kaluza-Klein resonances is often allowed and very
efficient. The observed dark matter abundance may then be obtained with
couplings of order unity and a compactification scale above the TeV. Light dark
matter is also possible in the presence of unsuppressed couplings to the Higgs
boson. In this latter case direct detection experiments will soon be able to
probe a significant portion of the parameter space.
