Based on the Veneziano ghost theory of QCD, we predict the cosmological constant A, which is related to energy density of cosmological vacuum by A = 3-8tG/pA. In the Veneziano ghost theory, the vacuum energy density PA is expressed by absolute value of the product of quark vacuum condensate and quark current mass： PA = 2g/Hclmq（OI ： qq ： 10）l- We calculate the quark local vacuum condensates （01 ： qq ： 10） by solving Dyson Schwinger Equations for a fully dressed confining quark propagator S/（p） with an effective gluon propagator G~b（q）. The quark current mass mq is predicted by use of chiral perturbation theory. Our theoretical result of A, with the resulting （01 ： qq ： ]0} = -（235 MeV）3 and light quark current mass rnq = 3.29 6.15 MeV, is in a good agreement with the observable of the A =10-52 m-2 used widely in a great amount of literatures.
