  The study of the associated production of vector bosons and jets constitutes
an excellent environment to check numerous QCD predictions. Total and
differential cross sections of vector bosons produced in association with jets
have been studied in pp collisions using CMS data. Differential distributions
as a function of a broad range of kinematical observables are measured and
compared with theoretical predictions. In this talk, studies of associated
production of vector bosons with inclusive jets and with jets originating from
heavy-flavour quarks will be summarized.
