Marie de Coucy was the daughter of Enguerrand III, Lord of Coucy and his third wife Marie de Montmirel (c. 1184 - 1267). She was Queen consort of the Kingdom of Scotland.
On May 15, 1239 she married King Alexander II of Scotland at Roxburgh, with whom she mothered the future King, Alexander III of Scotland. The marriage brought an alliance between the Scots and the Coucy lordship, and for the rest of the 13th century, they exchanged soldiers and money. Her husband died in 1249, and so two years later she returned to Picardy, although she would frequently revisit the Kingdom of Scotland.
Marie married King Alexander II 'the Peaceful' of Scotland, son of King William I 'the Lion' of Scotland and Queen Ermengarde de Beaumont of Scotland, on 15 May 1239 in Picardie, Picardie, France. (King Alexander II 'the Peaceful' of Scotland was born on 24 Aug 1198 in Haddington, East Lothington, Scotland, died on 6 Jul 1249 in Kerrera Island, Inner Hebrides and was buried in 1249 in Roxburgh, Roxburghshire, Scotland.)
