Recent results on the measurement of the dijet inclusive differential cross section and the dijet mass distribution made by the CDF and D0 collaborations are presented. The analyses are based on large statistics of data obtained from the 94-95 Tevatron collider run at Fermilab. The measured spectra are compared to QCD calculations using different parton distribution functions. The CDF and D0 dijet angular distributions are also presented to be compared to QCD calculations.
