Ibrahim II (died 1464) was a bey of Karaman. In 1425 he married Ilaldi Sultan Hatun, a daughter of Ottoman Sultan Mehmed I. They had six sons among them Ishak Bey, Pir Ahmet Bey and Kaya Bey, who married his cousin Hafsa Hatun, daughter of Murad II, and had a son, Kasım Bey.
During the post-Seljuk era in the second half of the 13th century, numerous Turkoman principalities, which are collectively known as the Anatolian beyliks, emerged in Anatolia. Initially the Karamanids, centered on the modern provinces of Karaman and Konya, were the most important power in Anatolia. But towards the end of the 14th century the Ottomans began to dominate most of Anatolia, reducing Karamanid influence and prestige. Thus the campaign of Timur to Anatolia and the ensuing Ottoman Interregnum gave the Karamanids a chance for revival. However the Karamanids also experienced a period of interregnum during Ottoman interregnum, so they were unable to end Ottoman domination in Anatolia.

Dulkadirids to capture the city of Kayseri and İsa, Ibrahim's brother, to capture Akşehir from Karamanids. Ibrahim was forced to lift the siege in 1437. During the following seven years peace prevailed in Anatolia.[3] But in 1444 when a great crusader army began marching on the Ottoman capital, Ibrahim saw his chance and plundered Ottoman cities in Anatolia including Ankara and Kütahya. Murat, caught between two fires, had to sign the Treaty of Szeged with the crusaders and then returned to Anatolia and retaliated. Ibrahim was forced to sign a treaty with unfavourable terms (called sevgendname). Although after Murat's death Ibrahim allied himself with Venice
