  Supersymmetric Twin Higgs models have a discrete symmetry for which each
Standard Model particle and its supersymmetric partner have a corresponding
state that transforms under a mirror Standard Model gauge group. This framework
is able to accommodate the non-discovery of new particles at the LHC with the
naturalness of the electroweak scale. We point out that supersymmetric Twin
Higgs models also provide a natural dark matter candidate. We investigate the
possibility that a twin bino-like state is the Lightest Supersymmetric Particle
and find that its freeze-out abundance can explain the observed dark matter
abundance without fine-tuning the mass spectrum of the theory. Most of the
viable parameter space can be probed by future dark matter direct detection
experiments and the LHC searches for staus and higgsinos which may involve
displaced vertices.
