Margaret Wilson (c. 1667 – 11 May 1685) was a young Scottish Covenanter from Wigtown in Scotland who was executed by drowning for refusing to swear an oath declaring James VII of Scotland (James II of England) as head of the church. She died along with Margaret McLachlan. The two Margarets were known as the Wigtown Martyrs. Wilson became the more famous of the two because of her youth. As a teenager, her faith unto death became celebrated as part of the martyrology of Presbyterian churches.
