A measurement of W -> enu + n-jet cross sections in p$\bar{p}$ collisions at <FONT FACE=Symbol>Ö</FONT>s = 1.96 TeV using the Collider Detector at Fermilab in Run II is presented. The measurement is based on an integrated luminosity of 320 pb-1, and includes events with jet multiplicity from > 1 to > 4. In each jet multiplicity sample the differential and cumulative cross sections with respect to the transverse energy of the n th-leading jet are measured. For W+ > 2 jets the differential cross section with respect to the 2-leading jets invariant mass m j1j2 and angular separation deltaRj1j2 is also reported. The data are compared to predictions from Monte Carlo simulations.
