We have carried out an accurate determination of the quadrupole moment of the deuteron nucleus. The evaluation of the constant is achieved by combining high accuracy Born-Oppenheimer calculations of the electric field gradient at the nucleus in the H2 molecule with spectroscopic measurements of the quadrupolar splitting in D2 and HD. The derived value is Q=0.285783(30) fm2.
