General (Kaïd) Sir Harry Aubrey de Vere Maclean, KCMG (15 June 1848 – 5 February 1920) was a Scottish soldier, and instructor to the Moroccan Army.
In 1876 he resigned from his regiment, and the following year he went to Morocco and began his career as an army instructor for the Sultan Mulai Hassan.
In June 1901 he was attached to a Special diplomatic mission from Morocco to the United Kingdom to congratulate King Edward VII on his recent accession, and the King appointed him a Knight Commander of the Order of St Michael and St George (KCMG) during the visit.
Although maintaining his Scottish personality and expert bagpipe skill, he adopted Moorish costume.
His portrait, by Sir John Lavery, hangs in the bar of the El Minzah Hotel in Tangier.
