  Recent progress in the perturbative analysis of hadronic jets, especially in
the context of hadron colliders, is discussed. The characteristic feature of
this work is the emergence of a level of precision in the study of the strong
interactions far beyond that previously possible. Inclusive cross sections for
high energy jets at the Tevatron are now perturbatively calculable with a
reliability on the order of 10%. At present this theoretical precision is
comparable to the quoted experimental errors. Progress has also been made
towards understanding both the internal structure of jets and the influence of
the details of the jet-defining algorithm.
