We present the preliminary results of a calculation of the fragmentation contribution to charmonium production at large transverse momentum in pp colliders. The fragmentation of gluons and charm quarks is the dominant direct production mechanism for sufficiently large p⊥. We find that for both J/ψ and ψ' production fragmentation dominates over the conventional gluon-gluon fusion mechanism for p⊥ greater than about 6 GeV. Presented at the Workshop on Physics at Current Accelerator and the Supercollider, Argonne National Laboratory, June 1993.
