We compute the topological susceptibility chi(t) in SU(3) lattice gauge theory using fermionic methods based on the Atiyah-Singer index theorem. Near the phase transition we find a smooth crossover behavior for chi(t) with values decreasing from (191(5) MeV)(4) to (100(5) MeV)(4) as we increase the temperature from 0.88T(c) to 1.31T(c), showing that topological excitations exist far above T-c. Our study is the first large scale analysis of the topological susceptibility at high temperature based on the index theorem and the results agree well with field theoretical methods.
