John Christian, Duke of Schleswig-Holstein-Sonderburg (Danish: Hans Christian af Slesvig-Holsten-Sønderborg, 26 April 1607 — 30 June 1653) used to be Duke of Schleswig-Holstein-Sonderburg from 1627 to his dying in 1653.
John Christian used to be the eldest son of Alexander, Duke of Schleswig-Holstein-Sonderburg and Dorothea, daughter of John Günther I, Rely of Schwarzburg-Sondershausen. His father had appointed him to be his successor. Alternatively, after his father died, his mom took over the management of the duchy, and John Christian used to be pressured to pay annual reimbursement for his brothers. This drew the duchy into deep debt. He died in Sønderborg in 1653, and used to be succeeded by way of his son Christian Adolf I.
