  The chiral Lagrangian for baryons is formulated in an expansion in 1/N_c. The
chiral Lagrangian implements the contracted spin-flavor symmetry of large-N_c
baryons as well as nonet symmetry of the leading planar diagrams. Large-N_c
consistency conditions ensure that chiral loop corrections are suppressed in
1/N_c through exact cancellation of chiral loop graphs to fixed orders in
1/N_c. Application of 1/N_c baryon chiral perturbation theory to the flavor-27
baryon mass splittings and the baryon axial vector currents are considered as
examples.
