Boulou Ferré (born Jean-Jacques Ferret, 24 April 1951) is a French virtuoso jazz guitarist, composer, arranger, and improviser. He is the brother of Elios Ferré, also a jazz musician, with whom he has recorded widely. His repertoire includes jazz and classical music. He is considered one of the greatest contemporary musicians of the manouche (gypsy jazz) tradition and has contributed to the genre through his knowledge of both jazz and classical music and his interest in the contrapuntal music of J. S. Bach.
