It really depends on the terminology used. According to the Wikipedia, "The term "asteroid" is ill-defined. It never had a formal definition, ..."
If you decide to include the dwarf planets, that would be Eris.
Note that there is practically a continuum in sizes, from grains of dust, all the way to the planets.
