  Preliminary results on a variety of jet analyses are presented using pp
collision data collected by the CMS experiment at $\sqrt{s}$=7 TeV. We report
on measurements of the inclusive jet cross sections, the ratio of the inclusive
three-jet over two-jet cross sections, the hadronic event shapes, the jet
structure and the dijet azimuthal decorrelations. The data distributions are
compared with the predictions of Monte Carlo event generators and with
perturbative QCD calculations.
