  A search is presented for dark matter produced in association with a
hadronically decaying W or Z boson using 3.2 /fb of pp collisions at
$\sqrt{s}$=13 TeV recorded by the ATLAS detector at the Large Hadron Collider.
Events with a hadronic jet compatible with a W or Z boson and with large
missing transverse momentum are analysed. The data are consistent with the
Standard Model predictions and are interpreted in terms of both an effective
field theory and a simplified model containing dark matter.
