The Battle of Baia (Romanian: Bătălia de la Baia; Hungarian: moldvabányai csata) was fought on December 15, 1467, between Moldavian prince Stephen the Great and the Hungarian king, Matthias Corvinus. Corvinus invaded Moldavia as a consequence of Stephen's annexation of Chilia—a fortress and harbour on the coast of the Black Sea—from Hungarian and Wallachian forces. It had belonged to Moldavia centuries earlier.
