We derive an effective action combining chiral and heavy-quark symmetry, using approximate bosonization techniques to QCD-inspired models of spontaneous symmetry breaking. We explicitly show that the heavy-quark limit is compatible with the large [ital N][sub [ital c]] (number of color) limit in the meson sector, and estimate the couplings between the light and heavy mesons ([ital D],[ital D][sup *], . . .) and their chiral partners to order one in the heavy-quark mass. The relevance of this effective action to solitons with heavy quarks is briefly discussed.
