Mary Macmaster (born 22 November 1955, Glasgow, Scotland) is a Scottish harpist and singer.
She has worked with Sting, Kathryn Tickell, Norma Waterson, Donald Hay, the Poozies, and in the duo Sìleas with Patsy Seddon.

During the same year, she started playing one of the first models of electric harp made by Joël Garnier.
[3] As of 2022, she oversees stage management as part of the team running the Edinburgh International Harp Festival.
