We argue that the dark energy that explains the observed accelerating expansion of the universe may arise due to the contribution to the vacuum energy of the QCD ghost in a time-dependent background. We show that the QCD ghost produces dark energy proportional to the Hubble parameter [Formula: see text] (ΛQCD is the QCD mass scale) which has the right magnitude ~ (3 × 10-3 eV)4.
