Princess Madeleine will step in as regent on behalf of her father, King Carl XVI Gustaf, as the monarch undertakes a private trip.
The Swedish head of state is travelling to Brazil for a family holiday with his wife, Queen Silvia, as well as their children and grandchildren.
Crown Princess Victoria, 47, who is heir to the Swedish throne will be among the family members on the trip along with her husband, Prince Daniel, and their children, Princess Estelle, 12, and Prince Oscar, eight.
Joining them will be Victoria's brother, Prince Carl Philip, 45, and his wife, Princess Sofia, 39, who is expecting the couple's fourth child next year. The pair are parents to three sons, Prince Alexander, eight, Prince Gabriel, seven, and Prince Julian, three.
Madeleine, who is King Carl Gustaf and Queen Silvia's youngest child, will not accompany her family on the trip.
The mother-of-three and her financier husband Christopher O'Neill moved back to Stockholm over the summer after residing in Florida for the last six years.
The Swedish palace's head of information, Margareta Thorgen, confirmed to Expressen that Madeleine would temporarily be stepping in as regent while the King is away between 25 October and 8 November.

Queen Silvia was born in Germany, but her mother Alice was Brazilian and the family lived in the South American country for ten years from when Silvia was four.
Madeleine, who is eighth in line to the throne, carries out official royal duties and she is Deputy Honorary Chair at her mother's organisation, the World Childhood Foundation.

The children are no longer styled His/Her Royal Highness (HRH) but they have retained their princely titles.
