t-quark physics at ILC

The top quark has not yet been studied in the extremely favorable and low-background environment of e+e- annihilation.   This talk will review the opportunities for precision measurements of the top quark properties at the  International Linear Collider.   These include the archival measurement of the top quark mass, the search for beyond-Standard-Model contributions to the top quark electroweak form factors, and the search for CP violation in the top quark couplings.
