Louise Alexandra Marie Irene Mountbatten (previously Princess Louise of Battenberg; 13 July 1889 – 7 March 1965) became Queen consort of Sweden in 1950 and served as such until her death in 1965. Through her marriage, prior to her husband's accession as King Gustaf VI Adolf, Louise was Crown Princess of Sweden and Duchess of Scania.

Louise was born a Princess of Battenberg at Schloss Heiligenberg, Seeheim-Jugenheim, in the Grand Duchy of Hesse. Her father, Prince Louis of Battenberg, who was Admiral of the Fleet in the United Kingdom, renounced his German title during World War I and anglicised his family name to "Mountbatten" at the behest of King George V. He was then created the first Marquess of Milford Haven in the peerage of the United Kingdom. From 1917, therefore, his daughter was known as "Lady Louise Mountbatten". Louise was a sister of Louis Mountbatten, 1st Earl Mountbatten of Burma, an aunt of Prince Philip, Duke of Edinburgh, and was also a niece of Empress Alexandra Feodorovna of Russia.

Because of her father's work, the family moved around between different British territories, such as Malta, but they returned often to the Heiligenberg outside Darmstadt which they considered their holiday home, always retaining residence in England. Louise often visited her great-grandmother, Queen Victoria, on the Isle of Wight with her mother during her childhood. The family is described as harmonious; the parents of Louise lived in a happy loving relationship, not in an arranged marriage, and Louise was particularly close to her brother, with whom she corresponded until her death. Louise and her sister were educated by governesses, except for a brief period at Texter's girls school in Darmstadt.
