  The CDF and D0 collaborations at Fermilab's Tevatron p-pbar collider have in
place an extensive program to measure fundamental properties of the top quark.
Recent results from Run I (sqrt-s = 1.8 TeV) and Run II (sqrt-s = 1.96 TeV) on
the top quark's production, mass, and decays are presented here. All results
are consistent within their uncertainties with the Standard Model expectations
for the top quark.
