Jules Delsart was a French cellist and teacher. He is best known for his arrangement for cello and piano of César Franck's Violin Sonata in A major. Musicologist Lynda MacGregor described Delsart as "one of the foremost French cellists of the period, with faultless technique, a precise bow and a sweet, though not large, tone." He was the owner of the 1689 'Archinto' Stradivari.
