QCD physics measurements at the LHCb experiment

The LHCb experiment offers a complementary phase space to ATLAS and CMS to study QCD processes, thanks to the forward acceptance and the large bandwidth of the trigger allowing low energy thresholds. For this reason QCD measurements at LHCb can provide unique constraints to the Parton Distribution Functions. Moreover these measurements can be used to probe perturbative QCD predictions, and to study hadronization processes. In these proceedings the latest QCD measurements that involve jets and performed during the Run II data taking are presented. In particular it is described how the measurement of the $Z$+$c$-jet production has been used to probe the instrinsic charm content of the proton.
