Éléonore Marie Desmier d'Olbreuse (3 January 1639 – 5 February 1722) was the wife of George William, Duke of Brunswick-Lüneburg. She was Countess of Wilhelmsburg from 1674 and Duchess of Brunswick-Lüneburg from 1676. She was the mother of Sophia Dorothea of Celle, who was the wife of George I. Thus she is the maternal grandmother of George II
Éléonore Desmier d'Olbreuse was born at the Castle of Olbreuse in Deux-Sèvres near Niort, France into a Huguenot family of lower nobility. Her parents were Alexandre Desmier d'Olbreuse and Jacquette Poussard du Bas-Vandré et de Saint-Marc. She went to the royal court in Paris as a lady-in-waiting in the service of Marie de la Tour d'Auvergne, Duchess of Thouars, whose son had married Emily of Hesse-Kassel, daughter of William V, Landgrave of Hesse-Kassel, in 1648.
In the winter of 1664 Éléonore accompanied the Duchess of Thouars who visited her son in Kassel. There the beautiful Éléonore met the unmarried George William, Duke of Brunswick-Lüneburg, who immediately fell in love with her.
Éléonore became his mistress and received the title Lady of Harburg. In 1666 their only child, Sophie Dorothea, was born. In 1674 the child was legitimised and Éléonore became the Duchess of Wilhelmsburg. Two years later the couple could finally marry. It was a happy marriage.
