  A measurement of the double-differential inclusive dijet production cross
section in proton-proton collisions at \sqrt{s}= 7 TeV is presented as a
function of the dijet invariant mass and jet rapidity. The data correspond to
an integrated luminosity of 36 pb^{-1}, recorded with the CMS detector at the
LHC in 2010. The measurement covers the dijet mass range 0.2 TeV to 3.5 TeV and
jet rapidities up to |y|=2.5. It is found to be in good agreement with
next-to-leading-order QCD predictions.
