The Battle of Baia is fought on December 15, 1467 between the Moldavian Prince Stephen the Great and Hungarian King Matthias Corvinus.

The battle is the last Hungarian attempt to subdue the independent Moldavia, as previous attempts had ended in failure.

Corvinus had invaded Moldavia as a consequence of Stephen's annexation of Chilia—a fortress and harbor at the coast of the Black Sea, which at this time is controlled by Hungarian and Wallachian forces, though it had belonged to Moldavia centuries earlier.The conflict endswith a bitter defeat for the Hungarians.

This puts an end to all Hungarian claims on Moldavia.
