Sigvard Oscar Fredrik, Prince Bernadotte, Count of Wisborg born as, and until 1934 known as, Prince Sigvard of Sweden, Duke of Uppland, was a member of the Swedish Royal Family and a successful industrial designer by profession.

The Swedish royal family since 1818 has consisted of members of the Swedish Royal House of Bernadotte, closely related to the King of Sweden. Today those who are recognized by the government are entitled to royal titles and styles, and perform official engagements and ceremonial duties of state. The extended family of the King consists of other close relatives who are not royal and thus do not represent the country officially.
