Abu Bakr II (fl. 14th century) may have been the ninth mansa of the Mali Empire. He succeeded his nephew Mansa Mohammed ibn Gao and preceded Kankou Musa I. Abubakari II appears to have abdicated his throne in order to explore "the limits of the ocean"; however, his expedition never returned.

What is known about the kings of the Malian Empire is taken from the writings of Arab scholars, including Al-Umari, Abu-sa'id Uthman ad-Dukkali, Ibn Khaldun, and Ibn Battuta. Lack of reliable documentation is a serious problem in this period, and Ibn-Khaldun's comprehensive history of the Malian kings does not list Abu Bakari as a mansa of Mali.

Abu Bakari II, sometimes called Abu Bekr II or Mansa Mohammed, was one of two sons of Kolonkan, a sister of the founding emperor Sundjata Keita.^{[citation needed]} He was the last of a mini-dynasty within the Keita clan of emperor's descending from Kolonkan. After his abdication in 1311, the Faga Laye mini-dynasty would control the empire.

Virtually all that is known of Abubakari II is from the scholar Al-Umari during Kankan Musa I's historic hajj to Mecca. While in Egypt, Musa explained the way that he had inherited the throne after the abdication of the previous ruler. He explained that in 1310, the emperor financed the building of 200 vessels of men and another 200 of supplies to explore the limits of the sea that served as the empire's western frontier. The mission was inconclusive, and the only information available on its fate came from a single boat whose captain refused to follow the other ships once they reached a "river in the sea" and a whirlpool. According to Musa I, his predecessor was undeterred and launched another fleet with himself as head of the expedition. In 1311, the previous ruler temporarily ceded power to Musa, then serving as his kankoro-sigui or vizier, and departed with a thousand vessels of men and a like number of supplies. After the emperor failed to return, Musa became emperor.

Abu Bakr (Abdullah ibn Abi Quhafa) (Arabic: عبد الله بن أبي قحافة, Transliteration: ʿAbd Allāh ibn Abī Quḥāfah, c. 573 CE - 634 CE) also known as Abū Bakr as-Șiddīq (Arabic: أبو بكر الصديق) was a senior companion (Sahabi) and the father-in-law of the Islamic prophet Muhammad. He ruled over the Rashidun Caliphate from 632–634 CE when he became the first Muslim Caliph following Muhammad's death. As Caliph, Abu Bakr succeeded to the political and administrative functions previously exercised by Muhammad, since the religious function and authority of prophethood ended with Muhammad's death according to Islam. He was called Al-Siddiq (The Truthful) and was known by that title among later generations of Muslims.

As a young man, Abu Bakr became a cloth merchant and he traveled extensively in Arabia and neighboring lands in the Middle East, through which he gained both wealth and experience. He eventually came to be recognized as the chief of his clan. On his return from a business trip to Yemen, he was informed that in his absence Muhammad had openly declared his prophethood. Not long after, Abu Bakr accepted Islam and was the first person outside the family of Muhammad to openly become a Muslim. He was instrumental in the conversion of many people to the Islamic faith and early in 623, Abu Bakr's daughter Aisha was married to Muhammad, strengthening the ties between the two men.
