Beatrice de Montfort, Countess of Montfort-l'Amaury (c. December 1248/1249 – 9 March 1312) was the wife of Robert IV of Dreux, Count of Dreux (1241 – 12 November 1282), and the ancestress of the Dukes of Brittany from the House of Montfort-Dreux which derived its name from her title.
Beatrice was born sometime between December 1248 and 1249, the only child of Jean I de Montfort, Count of Dreux and Jeanne, Dame de Chateaudun. Her paternal grandparents were Amaury VI, Count of Montfort and Beatrice of Burgundy, and her maternal grandparents were Geoffrey VI, Viscount de Chateaudun and Clémence des Roches. Her great- grandfather Simon de Montfort, 5th Earl of Leicester was a prominent leader of the Albigensian Crusade.
In 1249, Beatrice's father died in Cyprus, while participating in the Seventh Crusade, leaving her mother a widow. In 1251, Jeanne married her second husband, Jean de Brienne, Grand Butler of France. Jeanne and Jean had a daughter Blanche de Brienne, Baroness Tingry (1252–1302); Blanche married William II de Fiennes, Baron of Tingry. Jeanne died sometime after 1252, leaving her Beatrice and her half-sister Blanche as her co-heiresses.

He was the son of John I of Dreux, Count of Dreux and Braine, and Marie de Bourbon. The marriage produced six children.
