Alexander, Duke of Schleswig-Holstein-Sonderburg, (20 January 1573 – 13 May 1627) was a Danish nobleman.[1]
Alexander was born in Sønderborg (German: Sonderburg) in Schleswig, the third son of John II, Duke of Schleswig-Holstein-Sonderburg and Elisabeth of Brunswick-Grubenhagen. Because his elder surviving brother chose Ærø as his seat, Alexander received Sønderborg upon their father's death and was in practice its second duke. Alexander died in Sønderborg.
