The Little War (German: Kleinkrieg) is a series of conflicts between the Habsburgs and their allies and the Ottoman Empire between 1529 (after the Siege of Vienna) and 1552 (the end of the Siege of Eger).

The war sees both sides suffering heavy casualties with the result that campaigning in Hungary will not cease until 1566.

While overall, the Ottomans have the upper hand, the war fails to produce any decisive result.

The Ottoman army remains very powerful in the open field but it often loses a significant amount of time besieging the many fortresses of the Hungarian frontier and its communication lines are now dangerously overstretched.

At the end of the little war, the Turkish thrust into central Europe has effectively been stopped, but the Habsburg forces have failed in all their attempts to reclaim the whole of Hungary.
