Abstract	ATLAS measurements of vector boson production, inclusive and with associated jets in pp collisions in LHC Run1 will be presented. The results are compared to NLO Monte Carlo simulations and to NNLO QCD predictions corrected for NLO EW effects. The production of jets in association with a W or a Z boson is an important process to study QCD in a multiscale environment in pp collisions at the LHC. The production of heavy flavour in association with a W or Z boson is sensitive to the parton density functions and to the modeling heavyquark flavour production mechanisms.
