Patrick Lindsay, 6th Lord Lindsay of the Byres, (1521–1589), Scottish courtier and Confederate lord.
Patrick was the son of John Lindsay, 5th Lord Lindsay, who died in December 1563, and Helen Stewart, daughter of John, 3rd Earl of Atholl.
According to John Knox, Patrick Lindsay took up arms in May 1559 to prevent Perth falling into the hands of the Regent Mary of Guise after the riots of the Scottish Reformation. After he helped negotiate a treaty with the Regent's forces commanded by Henri Cleutin at Cupar Muir, Patrick had a share in the expulsion of the French garrison from Perth. After the Lords of the Congregation left Edinburgh in the spring of 1560, Patrick helped William Kirkcaldy of Grange to hold the French in check in Fife, and killed in single combat the French Captain La Bastie.
In February 1560 Patrick took part in the negotiation of the treaty of Berwick. On 27 April he subscribed the band to "defend the liberty of the Evangell of Christ", and he also subscribed the "Book of Discipline". He was one of those deputed by the General Assembly on 28 May 1561 to suppress "Idolatrie and all monuments thereof," and when Mary, Queen of Scots arrived from France in August 1561, and made known her intention of having mass said in her private chapel at Holyroodhouse, he and his followers gathered in front of it, exclaiming that "the idolater priest should die the death."Claude Nau asserts that he "drove the chaplain from the chapel and overthrew all the memorials," but Knox states that Lord James (afterwards Earl of Moray) kept the door and prevented Lindsay entering the chapel.
