Violet Mar (died 1577) was a Scottish woman accused of witchcraft and plotting the death of Regent Morton, the ruler of Scotland.
Violet lived at Kildeis or Keldeis in Muthill or Methven in Perthshire and was accused of using sorcery, witchcraft, incantations, and the invocation of spirits in her alleged plot against Morton.
He sought advice from his sister-in-law, Annabell Murray, Countess of Mar, who was the head of King James VI's household at Stirling Castle at the time.
The Laird of Abercairny intended to bring Violet Mar to Stirling, and Annabell Murray suggested he obtain written statements from her accusers.
It has been suggested that the Countess of Mar's involvement in such cases helped shape James VI's attitudes toward women accused of witchcraft.
