Abu Inan Faris (1329 – 10 January 1358) (Arabic: أبو عنان فارس بن علي) was a Marinid ruler of Morocco.

He extended his rule over Tlemcen and Ifriqiya, which covered the north of what is now Algeria and Tunisia, but was forced to retreat due to a revolt of Arab tribes there.

[2] However, Abu'l Hasan went too far in attempting to impose more authority over the Arab tribes, who revolted and in April 1348 defeated his army near Kairouan.

Abu Inan Faris, who had been serving as governor of Tlemcen, returned to Fez and declared that he was sultan.

Sultan Abul-Hajjaj of Granada hired ships from Castile and used them to take Abul-Fadl and his supporters to Sousse, where he launched a short-lived rebellion.

[3] Under Abu Inan's rule the Black Death and the rebellions of Tlemcen and Tunis marked the beginning of the decline of the Marinids.
