oboist and composer prominent in England in the first half of the 18th century and brother of Giovanni Battista Sammartini.

Giuseppe wrote an aria and sinfonia (both lost) for La Calumnia Delusa, which was performed in Milan in 1724. In about 1728 he went to London, where he remained for the rest of his life. He was much esteemed as a composer and as a performer, both in concert and at the opera. He entered the service of Frederick Louis, prince of Wales, for whom he wrote a setting of Congreve's Judgement of Paris. His works, written in the late Baroque style, include some trio sonatas and concerti grossi.
