After a brief introduction to left-right symmetric models, I will discuss different viable dark matter candidates in left-right supersymmetry, when the constraints from relic density and direct detection are taken into account. I will also discuss, how multilepton searches at the LHC could provide a signal of left-right supersymmetry through the resonant production of chargino-neutralino or slepton-sneutrino pairs.
