An overview of Run I jet physics at the ppbar Fermilab Tevatron Collider with
a particular emphasis on inclusive jet cross section measurements is given. The
impact of these studies on PDFs constrain from global fits is underlined.
Preliminary results on inclusive jet and di-jet mass cross section measurements
in Run II are then summarized.Comment: Presented at 15th Conference on High-Energy Physics (IFAE 2003),
