  We present a detailed study of dark matter phenomenology in low-scale
left-right symmetric models. Stability of new fermion or scalar multiplets is
ensured by an accidental matter parity that survives the spontaneous symmetry
breaking of the gauge group by scalar triplets. The relic abundance of these
particles is set by gauge interactions and gives rise to dark matter candidates
with masses above the electroweak scale. Dark matter annihilations are thus
modified by the Sommerfeld effect, not only in the early Universe, but also
today, for instance, in the Center of the Galaxy. Majorana candidates -
triplet, quintuplet, bi-doublet, and bi-triplet - bring only one new parameter
to the model, their mass, and are hence highly testable at colliders and
through astrophysical observations. Scalar candidates - doublet and 7-plet, the
latter being only stable at the renormalizable level - have additional
scalar-scalar interactions that give rise to rich phenomenology. The particles
under discussion share many features with the well-known candidates wino,
Higgsino, inert doublet scalar, sneutrino, and Minimal Dark Matter. In
particular, they all predict a large gamma-ray flux from dark matter
annihilations, which can be searched for with Cherenkov telescopes. We
furthermore discuss models with unequal left-right gauge couplings, $g_R \neq
g_L$, taking the recent experimental hints for a charged gauge boson with 2 TeV
mass as a benchmark point. In this case, the dark matter mass is determined by
the observed relic density.
