We partially analyze the two-loop box and hexagon chiral gauge anomalies in D = 6 and 10 dimensions for super-Yang-Mills theories. We apply these results to the SO(32) open superstring and show that the leading gauge anomaly vanishes at two-loop order while the subleading gauge anomalies, the mixed anomalies, and the subleading chiral gravitational anomalies may all be canceled with appropriate counterterms. To do this in field theory it is necessary to include a term B(TrF/sup 2/)/sup 2/ which is absent at one-loop order in the zero-slope limit of the SO(32) superstring.
