Al Bashir ibn Salim al-Harthi (Arabic: البشير بن سالم الحارثي) (c.1840 - 15 December 1889), was a wealthy merchant and slave-owning plantation owner of Omani Arab parentage who is known for the Abushiri Revolt against the German East Africa Company in present-day Tanzania.

Beginning on September 20, 1888, insurrections led by Abushiri attacked German-held trading posts and towns throughout the East African territory.

Al Bashir's forces were able to capture most of the towns along the Tanganyika coast and even took the explorers Hans Meyer and Oscar Baumann hostage.

[citation needed] Nevertheless, towards the end of 1888, much of his alliance with the local tribes had collapsed, and he was forced to hire Arab mercenaries to defend his stronghold at a fortress near Bagamoyo.

[1] After Abushiri accepted a truce with the Germans, troops led by Wissmann attacked the fortress on May 8, 1889, resulting in 106 Arab deaths.
