Ibn Jubayr (1 September 1145 -29 November 1217; Arabic: bn jbyr), also written Ibn Jubair, Ibn Jobair, and Ibn Djubayr, was an Arab geographer, traveller and poet from al-Andalus. His travel chronicle describes the pilgrimage he made to Mecca from 1183 to 1185, in the years preceding the Third Crusade.

Ibn Jubayr also travelled to Medina, Mecca, Damascus, Mosul, Acre and Baghdad at Basra he saw how Indian timber was carefully used to make Lateen sail ships, returning in 1185 by way of Sicily. His path was not without troubles, including a shipwreck. On both occasions he travelled on Genoese ships.  Frequently quoted is Jubayr's famous description of Muslims prospering under the Christian crusader Kingdom of Jerusalem:  We moved from Tibnin - may God destroy it - at daybreak on Monday. Our way lay through continuous farms and ordered settlements, whose inhabitants were all Muslims, living comfortably within the Franks... They surrender half their crops to the Franks at harvest time, and pay as well a poll-tax of one dinar and five qirat for each person. Other than that they are not interfered with, save for a light tax on the fruit of their trees. The houses and all their effects are left to their full possession. All the coastal cities occupied by the Franks are managed in this fashion, their rural districts, the villages and farms, belong to the Muslims. But their hearts have been seduced, for they observe how unlike them in ease and comfort are their brethren in the Muslim regions under their (Muslim) governors. This is one of the misfortunes afflicting the Muslims. The Muslim community bewails the injustice of the landlord of its own faith, and applauds the conduct of its opponent and enemy, the Frankish landlord, and is accustomed to justice from him.  Jubayr travelled to the East on two further occasions (1189-1191 and 1217), without leaving any account. He died on the 29 November 1217 in Alexandria during the second of these trips.
