Christian Frederik Bielke (8 May 1670 – 14 September 1709) was a Danish military officer.
In September he and Christian Gyldenløve returned to Denmark, where he was promoted to major and put in charge of a battalion in Oldenburg.
In 1708 he went abroad again when he was put in charge of a Prince Carl's Regiment battalion in English-Dutch service in Brabant.
In June 1709, he participated in the Conquest of Tournai and was on 11 September that same year wounded so severely in the Battle of Malplaquet that he died three days later.
[1] Bielke inherited Næsbyholm from his father but sold it in 1709 to Frederick IV.
