Daniel Maurice Alan Macmillan, Viscount Macmillan of Ovenden (born 9 October 1974) is the heir to Alexander Macmillan, 2nd Earl of Stockton.
Lord Macmillan is a great-grandson of the former Prime Minister Harold Macmillan, 1st Earl of Stockton and he holds a courtesy title, through his father. In 2003 he designed and launched the Zoltar fashion label with Kieron Livingstone as creative director.
In addition to his clothing label, Macmillan has worked as a model, an actor, and photographer. He is said to have dated Kate Moss and Jade Jagger.
Macmillan does not plan on entering the family publishing business, after his father sold it to a German publisher in the 1990s. He is heir to a £200 million fortune.
