Ibn Tufail (c. 1105, Guadix, Andalusia – 1185) (full Arabic name: أبو بكر محمد بن عبد الملك بن محمد بن طفيل القيسي الأندلسي Abu Bakr Muhammad ibn Abd al-Malik ibn Muhammad ibn Tufail al-Qaisi al-Andalusi; Latinized form: Abubacer Aben Tofail; Anglicized form: Abubekar or Abu Jaafar Ebn Tophail) was an Andalusian Muslim polymath: a writer, novelist, Islamic philosopher, Islamic theologian, physician, vizier, and court official.

As a philosopher and novelist, he is most famous for writing the first philosophical novel, Hayy ibn Yaqdhan, also known as Philosophus Autodidactus in the Western world. As a physician, he was an early supporter of dissection and autopsy, which was expressed in his novel.

Born in Guadix near Granada, he was educated by Ibn Bajjah (Avempace). He served as a secretary for the ruler of Granada, and later as vizier and physician for Abu Yaqub Yusuf, the Almohad king, to whom he recommended Ibn Rushd (Averroës) as his own future successor in 1169. Ibn Rushd later reports this event and describes how Ibn Tufayl then inspired him to write his famous Aristotelian commentaries:

Ḥayy ibn Yaqẓān (Arabic: حي بن يقظان‎ "Alive, son of Awake"; Latin: Philosophus Autodidactus "The Self-Taught Philosopher"; English: The Improvement of Human Reason: Exhibited in the Life of Hai Ebn Yokdhan) is an Arabic philosophical novel and allegorical tale written by Ibn Tufail in the early 12th century.

He was a prolific author, writing juvenile fiction, brief histories, biographies, religious books for the general reader, and a few works in popular science.
