Margaret Macpherson Grant (27 April 1834 – 14 April 1877) was a Scottish heiress and philanthropist. Born in Aberlour parish to a local surgeon, she was educated in Hampshire, and was left an only child when her elder brother died in India in 1852. Two years later, she inherited a large fortune from her uncle, Alexander Grant, an Aberlour-born planter and merchant who had become rich in Jamaica.
