  Twenty years after its discovery in 1995 by the CDF and D0 collaborations at
the Tevatron proton-antiproton collider at Fermilab, the top quark still
undergoes intensive studies at the Tevatron and the LHC at CERN. In this
article, recent top quark physics results from CDF and D0 are reported. In
particular, measurements of single top quark and double top quark production,
the ttbar forward-backward asymmetry and the top quark mass are discussed.
