The Jelveti order (also spelled Celvetîyye) is a Sufi order (tariqa) within Sunni Islam, founded by Aziz Mahmud Hudayi.
The Jelveti order did not spread as widely as some other Sufi paths and remained primarily within the borders of modern Turkey, though it maintained several tekkes in the Balkans. Notable Jelveti sheikhs include Bursalñ ðsmail Hakkñ of Bursa, Osman Fazlñ, and Mustafa Devati. In Ottoman Bosnia, a prominent Jelveti leader was Mustafa Gaibi.
