Valdemar Christian of Schleswig-Holstein (Danish: Valdemar Christian til Slesvig og Holsten; 1622–29 February 1656) was the son of king Christian IV of Denmark and his morganatic spouse Kirsten Munk.

Born as the youngest legitimate son of King Christian IV of Denmark, he had a tough childhood.

His elder half-brother Ulrik had succeeded (under the name Ulrich III) his uncle as a bishop of Schwerin.

He was raised under the supervision of the royal governess Karen Sehested.

In 1648, he came into conflict with his half-brother Prince Frederik because of his wish to be elected king instead of Frederick, and after this, he lived abroad.
