  A new type of dark matter (DM) theories are proposed in the light of the
standard model (SM) singlet scalar $\phi$ which is responsible for the diphoton
excess at the LHC Run 2. In the so-called $\phi$-portal DM models, after taking
into account the LHC constraints and DM direct detection limits, we show that
in the perturbative framework DM as either a SM singlet scalar or Dirac fermion
can be allowed in a wide mass range between 400 GeV and 3 TeV. The DM can be
directly detected in SM multi-jets and missing energy.
