We present some of the most recent QCD results from DØ. The Run I measurement of the inclusive k T jet cross section is one of the first analyses on hadron-hadron colliders that uses the k T -algorithm instead of the traditional cone one. We observe a good agreement with NLO QCD predictions and also with the previous Run I measurement which utilised the cone algorithm. The agreement is marginal at low p T end. The difference is attributed to the different behaviour of jet algorithms after hadronization. We also present preliminary Run II results on the inclusive jet cross section and the inclusive dijet mass spectrum. The analysis is performed on the sample of . Due to a 9% increase in the center of mass energy and a higher instantaneous luminosity, in the near future, the Run II data will provide greater statistics for high p T jets than in Run I.
