Meson loop corrections to baryon axial currents are computed in the 1/N
expansion. It is already known that the one-loop corrections are suppressed by
a factor 1/N; here it is shown that the two-loop corrections are suppressed by
(1/N)^2. To leading order, these corrections are exactly what would be
calculated in the constituent quark model. Some applications are discussed.
