Guy of Thouars (died 13 April 1213) was the third husband of Constance, Duchess of Brittany, whom he married in Angers, County of Anjou between August and October 1199[a][1] after her son Arthur of Brittany entered Angers to be recognized as count of the three countships of Anjou, Maine and Touraine. He was an Occitan noble, a member of the House of Thouars. He is counted as a duke of Brittany, jure uxoris, from 1199 to 1201.

Between 1196 and the time of her death in 1201, while delivering twin daughters, Constance ruled Brittany with her young son Arthur I, Duke of Brittany as co-ruler. Duke Arthur I was captured in 1202 by their uncle John, King of England and disappeared in 1203; with his full elder sister Eleanor, Fair Maid of Brittany captured along with him and imprisoned by John, he was succeeded by his infant maternal sister, Alix of Thouars. Guy served as Regent of Brittany for his infant daughter Alix from 1203 to 1206.

In 1204, Guy de Thouars as regent of Duchess Alix, vassal of Philip II, King of France, undertook the siege of the Norman island fortress of Mont Saint-Michel. Because the abbey would not surrender, he set fire to the village and massacred the population. He was obliged to beat a retreat under the powerful walls of the abbey. The fire which he himself lit extended to the buildings, and the roofs were engulfed in flames. Philip II paid Abbot Jordan for the reconstruction cost.

In 1206 Philip II took the regency of Brittany himself, much to the consternation of the Breton nobles.[b]

Guy of Thouars died in 1213 in Chemillé in the county of Maine, and was buried with Constance at Villeneuve Abbey, now in the commune of Les Sorinières, outside of Nantes. 'Situated at Nantes south gate, Abbey de Villeneuve' was 'founded in 1201 by Constance de Panthièvre, the Duchess of Brittany ...'[2]
