The evidence of top quark pair production in ppbar collisions has
been firmly established by both the CDF and the D0 collaborations at Fermilab.
In this paper the latest top quark physics results from both experiments at
the Tevatron Collider are presented.  The experimental analyses have
concentrated in improving the accuracy of top quark production and decay
measurements like cross sections, mass and branching fractions.  The results
shown correspond to the final data set collected with both detectors during
the complete Tevatron Run I.  This represents a total recorded integrated
luminosity of \sim 110 pb^-1 for CDF and \sim 100 pb^-1 for D0.
