Ingrid of Sweden (Ingrid Victoria Sofia Louise Margareta; 28 March 1910 – 7 November 2000) was Queen of Denmark from 1947 until 1972 as the wife of King Frederick IX.
Born into the House of Bernadotte, she was the daughter of King Gustaf VI Adolf of Sweden and his first wife, Princess Margaret of Connaught. In 1935, she married Crown Prince Frederick of Denmark and they had three daughters: Margrethe, the current Queen of Denmark; Benedikte, now a Princess of Sayn-Wittgenstein-Berleburg; and Anne-Marie, the former Queen of the Hellenes.
In 1947, her husband became king on his father's death. As queen, Ingrid reformed the traditions of Danish court life, abolished many old-fashioned customs at court and created a more relaxed atmosphere at official receptions. King Frederick IX died in 1972, and Ingrid's daughter Margrethe became queen.
She was also a paternal aunt of the present Swedish monarch, King Carl XVI Gustaf.
