  The top quark is by far the most massive fundamental particle observed so
far, and the study of its properties is interesting for several reasons ranging
from its possible special role in electroweak symmetry breaking to its
sensitivity to physics beyond the Standard Model. We present recent top physics
results from CDF based on 160-320 inverse pb of ppbar collision data at a
center-of-mass energy of 1.96 TeV. The ttbar cross section and the top mass
have been measured in different decay channels and using different methods. We
have searched for evidence of single top production, setting upper limits on
its production rate. Other results shown in this conference include studies of
the polarization of W bosons from top decays, a search for charged Higgs
decaying from top, and a search for additional heavy t' quarks.
