Sundiata Keita (Mandinka, Malinke: [sʊndʒæta keɪta]; c. 1217 – c. 1255, N'Ko spelling: ߛߏ߲߬ߖߘߊ߬ ߞߋߕߊ߬; also known as Manding Diara, Lion of Mali, Sogolon Djata, son of Sogolon, Nare Maghan and Sogo Sogo Simbon Salaba) was a prince and founder of the Mali Empire. He was also the great-uncle of the Malian ruler Mansa Musa, who is regarded as the wealthiest person of all time, although there are no reliable ways to accurately calculate his wealth.

Written sources augment the Mande oral histories, with the Moroccan traveller Muhammad ibn Battúta (1304–1368) and the Tunisian historian Ibn Khaldun (1332–1406) both having travelled to Mali in the century after Sundiata's death, and providing independent verification of his existence. The semi-historical but legendary Epic of Sundiata by the Malinké/Maninka people centers on his life. The epic poem is primarily known through oral tradition, transmitted by generations of Maninka griots (djeli or jeliw). The Manden Charter issued during his reign is listed by UNESCO as one of an intangible cultural heritage.

The Sundiata Epic has previously been interpreted  as a mystical epic of the Mali Empire with emphasis placed on its heroic dimensions. However, the religious context in which the epic was preserved warrants the consideration of Islam’s role in the epic. The oral traditions maintained by griots developed within an Islamic intellectual and cultural environment.

The oral traditions relating to Sundiata Keita were passed down generation after generation by the local griots (djeli or jeliw), until eventually their stories were put into writing. Sundiata was the son of Naré Maghann Konaté (variation: Maghan Konfara) and Sogolon Condé (variations: "Sogolon Kolonkan" or "Sogolon Kédjou", the daughter of the "buffalo woman", so-called because of her ugliness and hunchback). Sundiata was crippled from childhood and his mother (Sogolon) was the subject of ridicule among her co-wives. She was constantly teased and ridiculed openly for her son's disability. This significantly affected Sundiata and he was determined to do everything he possibly could in order to walk like his peers. Through this determination, he one day miraculously got up and walked. Among his peers, he became a leader. His paternal half-brother, Dankaran Touman, and Dankaran's mother, Sassouma Bereté, were cruel and resentful of Sundiata and his mother. Their cruelty escalated after the death of Naré Maghann (the king and father of Sundiata). To escape persecution and threats on her son's life, Sogolon took her children, Sundiata and his sisters, into exile. This exile lasted for many years and took them to different countries within the Ghana Empire and eventually to Mema, where the king of Mema granted them asylum. Sundiata was admired by the King of Mema for his courage and tenacity. As such, he was given a senior position within the kingdom. When King Soumaoro Kanté of Sosso conquered the Mandinka people, messengers were sent to go and look for Sogolon and her children, as Sundiata was destined to be a great leader according to prophecy. Upon finding him in Mema, they persuaded him to come back in order to liberate the Mandinkas and their homeland. On his return, he was accompanied by an army given to him by the King of Mema. The warlords of Mali at the time who were his age group included: Tabon Wana, Kamadia Kamara (or Kamadia Camara), Faony Condé, Siara Kuman Konaté and Tiramakhan Traore (many variations: "Trimaghan" or "Tiramaghan", the future conqueror of Kaabu). It was on the plain of Siby (var: Sibi) where they formed a pact brotherhood in order to liberate their country and people from the powerful Sosso king. At The Battle of Kirina, Sundiata and his allies defeated the Sosso king, and he became the first Emperor of the Mali Empire. He was the first of the Mandinka line of kings to adopt the royal title Mansa (king or emperor in the Mandinka language).

The Mandinka epic does not give us dates, but Arab and North African writers who visited the area about a century after the epic's events documented on paper some of the information, including dates and a genealogy. Conversely, the written sources left out other pieces of information that the oral tradition includes.

The proper English spelling of Sundiata's name is Sunjata, pronounced soon-jah-ta, approaching the actual pronunciation in the original Mandinka. The name Sogolon derives from his mother and Jata means lion. It is the traditional way of praising someone in some West African societies (Gambia, Senegal, Mali and Guinea in particular). The name Sundiata praises him through his mother which means "the lion of Sogolon" or "Sogolon's lion". The name Jata derives from Jara (lion). Jara and many of its variations such as jata, jala or jada are merely regional variations, from Gambia, Guinea or Mali, for instance. Sundiata's name is thus a derivation of his mother's name Sogolon (Son or its variation Sun) and Jata (lion).

Although there is no evidence that Sunjata himself practiced Islam, the chronicle has a lot of references to Islamic ideas and social structures that reflect the religious environment of West Africa at the time of Sundiata’s reign. The rise of the nyamakala class, specifically griots, demonstrates how oral traditions preserved not only the epic of Sundiata, but the evolving cultural influences. The story of Surakata for insurance symbolizes the griot tradition and the birth of a system that redefined honor. Through this, Islamic intellectual culture inevitably became embedded within the storytelling tradition even if the epic itself is Mande rooted.

Some Bambaras and Mandinkas have proposed that the name Keita actually means inheritor (heir-apparent) in the Mandinka language, and that Sundiata's real surname is Konaté (French spelling in Mali) or Konateh, variations: Konate, Conateh (English spelling in the Gambia where the Mandinkas make up the largest ethnic group). It is proposed that Sundiata Keita's father, Naré Maghann Konaté, took the real family name Konaté while his successors were "Keitas in waiting" (heirs to the throne). The name Keita is a clan name rather than a surname. Although in some West African societies a clan can be similar to the family name (see Joof family), such similarities do not exist between the names Keita and Konaté. Both points of contention agree that Keita is not a real surname, but rather a royal name, in spite of the fact that Sundiata is referred to as Sundiata Keita in many scholarly works. At present, there is no consensus among the scholars regarding the name Sundiata Konaté.^{[citation needed]}
