Presented are the latest results on jet fragmentation studies carried out by the CDF Collaboration. Charged particle multiplicities and momentum distributions are measured for quark and gluon jets. The multiplicities are compared to pQCD calculations and earlier results from e⁺ e^- colliders. Jet shapes for a broad range of jet transverse momenta are measured and compared to Pythia and Herwig Monte Carlo event generator predictions.
