Máel Muire of Atholl was Mormaer of Atholl at the beginning of the 12th century, until sometime perhaps in the 1130s. According to the Orkneyinga Saga, Máel Muire was a son of king Donnchad I and a younger brother of King Máel Coluim III. A Malmori d' Athótla is mentioned in a charter relating to a year after 1130, contained within the Book of Deer.
