Yolande of Dreux (1263 – 2 August 1330) was a sovereign Countess of Montfort from 1311 until 1322. Through her first marriage to Alexander III of Scotland, Yolande became Queen consort of the Kingdom of Scotland. Through her second marriage to Arthur II, Duke of Brittany, she became Duchess Consort of Brittany.
She was the daughter of Robert IV, Count of Dreux, and Beatrice, Countess of Montfort. Her father was a patrilineal descendant of King Louis VI of France, making her a member of a cadet branch of the Capetian dynasty with powerful connections.
In 1281, King Alexander III of Scotland lost his son David and two other children in the two following years, leaving his granddaughter, Margaret, Maid of Norway, as his heir presumptive. He was in need to remarry to have a new heir to the throne. Yolande was the stepdaughter of Jean de Brienne, the second spouse of king Alexander's mother, queen dowager Marie de Coucy, and considered a suitable match. Yolande was related to her husband Alexander III, through shared ancestry in the French noble houses of Coucy and Dreux. In addition to providing an heir for the Kingdom of Scotland, Alexander's marriage to Yolande represented a move to distance Alexander from his neighbour Edward I of England and to emphasize Scottish independence from England.
An embassy was sent from Scotland in February 1285 and returned with Yolande in the company of her brother Jean. The marriage was celebrated on 15 October 1285 at Jedburgh Abbey, attended by a great many nobles of France and Scotland.
Alexander died on either 18 March or 19 March 1286, after falling from his horse, while riding from his court at Edinburgh to join Yolande at Kinghorn. Following his death, queen dowager Yolande moved to Stirling Castle and declared that she was pregnant. The Guardians of Scotland were elected by a parliament held at Scone, Perth and Kinross on 2 April or 28 April 1286 and swore to govern the kingdom until Alexander's declared heir Margaret of Norway arrived to take the throne or Yolande gave birth to a child who would be preferred over Margaret.
It is unclear what happened to her pregnancy; either she had a miscarriage, or the baby was stillborn or died shortly after birth. However, by one account the Guardians gathered at Clackmannan on Saint Catherine's Day — 25 November 1286 — to witness the birth, but the child was stillborn. Tradition says the baby was buried at Cambuskenneth. After the queen dowager's pregnancy did not result in a living child, the council begun preparations for Margaret of Norway to be taken to Scotland as their new sovereign.
Queen dowager Yolande remained in Scotland for a couple of years supported by her dower provisions and living possibly at Stirling Castle: it is known that she was still in Scotland at least as late as in 1288. At some point, she returned to France.
Yolande succeeded her mother as suo jure Countess of Montfort in 1311. She continued to manage her Scottish affairs: as late as shortly before her death, she is noted to have sent a knight to Scotland to see to her dower lands.
Yolande died on 2 August 1330. Her county of Montfort passed to her son John, who would later fight for his claim to his father's duchy in the Breton War of Succession.
Yolande and Arthur had at least six children:
- John, born c. 1294, later Count of Montfort – known as Jean de Montfort
- Beatrice, born c. 1295, married Guy X of Laval
- Joan, born c. 1296, married Robert, son of Robert III of Flanders
- Alice, born c. 1297–1377, married Bouchard VI of Vendôme
- Blanche, born c. 1300, died young
- Marie, born c. 1302, entered a convent
