Prince Christian Nikolaus of Schaumburg-Lippe (; 20 February 1898 – 13 July 1974) was a German prince and head of the Náchod branch of the princely house of Schaumburg-Lippe.
He was born on 20 February 1898 in Sopron, Hungary, as the only son and second child of Frederick of Schaumburg-Lippe and his first wife Princess Louise of Denmark, younger sister of King Christian X of Denmark.
In World War I, Prince Christian served as an officer of the Imperial German Army and was awarded both classes of the Iron Cross, among other decorations.
Together with his wife, he took part in the ship tour organized by Queen Frederica and her husband King Paul of Greece in 1954, which became known as the "Cruise of the Kings" and was attended by over 100 royals from all over Europe. He died aged 76 on 13 July 1974 at Bückeburg, a year before his wife.
In 1927, his engagement to Princess Irene of Greece and Denmark, a daughter of Constantine I of Greece was announced. However, nothing went as planned. She later married Prince Aimone of Savoy-Aosta.
He was also briefly considered as a marriage candidate for Princess Juliana, the heiress to the Dutch throne. They had met each other in 1932 in Mecklenburg, home of JulianaâÂÂs paternal relations. Although his reputation as a womanizer, his previous called off engagement and his German heritage did not make him a popular choice, he was reconsidered after other candidates were rejected by the Queen or Juliana herself. These plans, however, did not prove fruitful either.
On 9 September 1937, he married his cousin, Princess Feodora, daughter of his maternal uncle Prince Harald of Denmark who was a younger brother of King Christian X and Princess Louise, at Fredensborg Palace, Zealand, Denmark; they had four children.
