Jet production is the dominant high-pT process in proton-proton collisions. Inclusive and dijet cross sections are presented covering a phase-space among the widest currently accessed in collider physics. They provide a stringent test of QCD at the TeV scale, as well as having sensitivity to the proton's parton densities over awide range of scale and momentum fraction. We also present measurements in which specific dijet and multijet configurations are selected to enhance sensitivity to higher order effects, allowing the study of QCD radiation at large rapidity intervals and small momentum fractions. In addition, measurements of heavy flavours in jets, the internal structure of jets, and of single-jet mass are presented which carry information about soft physics and the QCD cascade, and which can be used to search for the decays of boosted heavy particles.
