  We explore the possibility that the recently reported diphoton excess at
ATLAS and CMS can be accommodated within a minimal extension of a left-right
symmetric model. Our setup is able to simultaneously explain the Run 2 diphoton
and Run 1 diboson excesses, while providing a standard thermal freeze-out of
weak-scale dark matter. In this scenario, the 750 GeV neutral right-handed
Higgs triplet is responsible for the diphoton excess. Interactions of this
state with the neutral and charged components of dark matter multiplets provide
the dominant mechanisms for production and decay. A striking signature of this
model is the additional presence of missing energy in the diphoton channel.
