Birgitte, Duchess of Gloucester, GCVO (born Birgitte Eva Henriksen on 20 June 1946; later van Deurs), is the wife of Prince Richard, Duke of Gloucester, who is a grandson of King George V and Queen Mary, and first cousin of Queen Elizabeth II.

Birgitte was born Birgitte Eva Henriksen, in Odense, Denmark, the younger daughter of Asger Preben Knud Wissing Henriksen, a lawyer, and his wife, Vivian van Deurs, a Dutch woman. After their divorce, her father married Emma Neergaard Rasmussen, the future wife of magnate Mærsk Mc-Kinney Møller.
She took her mother’s ancestral name van Deurs on 15 January 1966, when her parents separated. She moved to Cambridge, England, and also worked at the Danish Embassy in London.

In February 1972, Birgitte became engaged to Prince Richard of Gloucester, the younger son of Prince Henry, Duke of Gloucester and Princess Alice, Duchess of Gloucester.
