The top quark plays an important role in the grand scheme of particle physics, and is also interesting on its own merits. We present recent results from CDF on top-quark physics based on 100-200 pb-1 of p anti-p collision data. We have measured the tt-bar cross section in different decay modes using several different techniques, and are beginning our studies of top-quark properties. New analysis for this conference include a measurement of sigma_tt-bar in the lepton-plus-jets channel using a neural net to distinguish signal and background events, and measurements of top-quark branching fractions.
