Janet Douglas, Lady Glamis (c. 1498 – 17 July 1537) was a Scottish noblewoman accused of attempted murder, who was executed by burning during the reign of James V of Scotland.
However, James called her "our lovittis Dame Jonat Douglas" in a licence of 1529, allowing her and a co-accused Patrick Charteris of Cuthilgurdy to go on pilgrimage, and be exempt from legal proceedings.
A recent historian, Jamie Cameron, thinks it unlikely that Janet went on pilgrimage, as she was the subject of a number of legal actions culminating in a charge of poisoning her husband John Lyon, 6th Lord Glamis who had died on 17 September 1528.
However, on 17 July 1537, Janet was convicted of planning to poison the King, and communicating with her brothers, the Earl of Angus and George Douglas.
