Christian Detlev, Count von Reventlow (1671–1738) was a Danish military leader and diplomat. He was the son of Conrad, Count Reventlow, chancellor of Denmark and half-brother of Anne Sophie Reventlow, queen consort of Denmark and, initially, morganatic wife of Frederick IV of Denmark.
Reventlow had a military career. He fought in the Danish contingent against the French in the War of the Grand Alliance.
In 1701 he was sent at the head of the Danish troops to fight the French in Italy in the War of Spanish Succession. He served under Eugene of Savoy, but had to face the French alone in the Battle of Calcinato in 1706. Outnumbered, and pitted against the able general Vendôme, Reventlow had little likelihood of success.
In 1709 he held command of Danish forces in Scania during the Great Northern War.
In March 1713 King Frederick IV appointed Reventlow as president of Altona. The city had been plundered by the Swedish, and had to be rebuilt. His task was to supervise the reconstruction program. In 1732 he was dismissed as president of Altona after the death of his brother in law, Frederick IV.
Among his children:
- Christian Ditlev Reventlow (1710–1775)
- Conrad Detlev, married in 1731 Wilhelmina Augusta (1704–1749), daughter of Prince Christian Charles of Schleswig-Holstein-Sonderburg-Plön-Norburg;
- Christine Armgard von Reventlow (1711-1779), married Frederick Charles, Duke of Schleswig-Holstein-Sonderburg-Plön and had issue.
