The rebab (Arabic الربابة or ربابة : "bowed instrument"), also rebap, rabab, rebeb, rababah, or al-rababa is a type of string instrument so named no later than the 8th century and spread via Islamic trading routes over much of North Africa, the Middle East, parts of Europe, and the Far East.

The bowed variety often has a spike at the bottom to rest on the ground, and is thus called a spike fiddle in certain areas, but there exist plucked versions like the kabuli rebab (sometimes referred to as the robab or rubab).
