John Adolph of Schleswig-Holstein-Sonderburg-Norburg (German: Johann Adolf or Hans Adolf; 15 September 1576 – 21 February 1624), was a Duke of Norburg at Als.
He was the son of John II of Schleswig-Holstein-Sonderburg and his wife Elizabeth of Brunswick-Grubenhagen.
When his father died in 1622, he inherited the area around the Norburg on the island of Als and thus became the first Duke of Schleswig-Holstein-Sonderburg-Norburg.
He was engaged to Maria Hedwig, a daughter of Duke Ernest Louis of Pomerania-Wolgast.
His brother Frederick inherited his title and his land.
