William Manderstown (c.1485–1552) was a Scottish philosopher and Rector of the University of Paris.
He was born in the diocese of St. Andrews, probably at the town of Manderston, Stirlingshire. Educated apparently at St. Andrews, he subsequently proceeded to the University of Paris, where he graduated licentiate in medicine, and became one of the school of Terminists, at whose head was John Mair. On 15 Dec. 1525 he was chosen one of the rectors of the university of Paris. Before 1539 he had returned to Scotland, for in that year, along with John Mair, he founded a bursary or chaplaincy in St. Salvator's, and endowed it with the rents of houses in South Street, St. Andrews. On 3 April in the same year Manderstown witnessed a charter at Dunfermline Monastery, and also appears as rector of Gogar.
In 1518 Manderstown published at Paris two works, Bipartitum in Morali Philosophia Opusculum, dedicated to Andrew Forman, and Tripartitum Epithoma Doctrinale; in the latter he was later said to have plagiarised from Jérôme de Hangest. Besides these, Thomas Tanner attributes to Manderstown: 1. In Ethicam Aristotelis ad Nicomachum Comment; 2. Quæstionem de Futuro Contingenti; 3. De Arte Chymica.
