The two-nucleon contributions to the electric dipole moment (EDM) of the deuteron, induced by the QCD θ-term, are calculated in the framework of effective field theory up-to-and-including next-to-next-to-leading order. In particular we find for the difference of the deuteron EDM and the sum of proton and neutron EDM induced by the QCD θ-term a value of 
e fm. The by far dominant uncertainty comes from the CP- and isospin-violating πNN coupling constant.
