Unico Wilhelm, Count van Wassenaer Obdam (30 October 1692 – 9 November 1766) was a Dutch nobleman who was a diplomat as well as a composer. He reorganized the Bailiwick of Utrecht of the Teutonic Order. His most important surviving compositions are the Concerti Armonici, which until 1980 had been misattributed to the Italian composer Giovanni Battista Pergolesi (1710–1736) and to Carlo Ricciotti (1681–1756).
