Frederick of Schleswig-Holstein-Sonderburg-Norburg (26 November 1581, in Sønderborg – 22 July 1658, in Nordborg) was Duke of Schleswig-Holstein-Sonderburg-Norburg.
Frederick was the youngest son of John, Duke of Schleswig-Holstein-Sonderburg and his first wife, Elisabeth of Brunswick-Grubenhagen. Since Frederick was the youngest son, no duchy was originally provided for him. However, after the death of his brother John Adolph in 1624, he inherited his brother's title and duchy.
Frederick married on 1 August 1627 Juliana, daughter of Francis II, Duke of Saxe-Lauenburg. The couple had one son:
After the death of his first wife in 1630, Frederick married on 5 February 1632 Eleanor of Anhalt-Zerbst (10 November 1608, Zerbst – 2 November 1680, Osterholm), daughter of Rudolph, Prince of Anhalt-Zerbst. The couple had the following children:
After Frederick's death in 1658, his eldest son inherited the title; his widow, Eleanor von Anhalt-Zerbst, acted as guardian.
