The Ottoman conquest of Bosnia is a process that had started roughly in 1384, when the first Ottoman attacks on the Kingdom of Bosnia took place.

In 1451, more than sixty-five years after its initial attacks, the Ottoman Empire officially established the Bosansko Krajište, an interim borderland military administrative unit, an Ottoman frontier, in parts of Bosnia and Herzegovina.

In 1463, the Kingdom falls to the Ottomans, and this territory comes under its firm control.
