Alexander Abercromby of Glassaugh, Fordyce, Banffshire (5 November 1678 – 23 December 1728) was a Scottish Army officer and politician who sat in the Parliament of Scotland from 1706 to 1707 and as a Whig in the British House of Commons from 1707 to 1727. In 1699 he inherited Tullibody House east of Stirling from his cousin George Abercromby. He remodeled the house in 1710 and in 1719 additionally acquired the nearby Menstrie Castle. Abercromby was a book collector who had a significant private collection, and books bearing his bookplate can still be found in libraries today.
