Muhammad I al-Mustansir (Arabic: أبو عبد الله محمد المستنصر, romanized: Abu Abd Allah Muhammad al-Mustansir ibn Yahya; c.1228–1277) was the second Sultan of Ifriqiya of the Hafsid dynasty and the first to claim the title of Khalif. Al-Mustansir concluded a peace agreement to end the Eighth Crusade launched by Louis IX of France in 1270. Muhammad I al-Mustansir had been a vassal of the Kingdom of Sicily, but had shaken off his allegiance when King Manfred was overthrown by King Charles I.
