The Knight's Cross of the Iron Cross (German: Ritterkreuz des Eisernen Kreuzes) and its variants were the highest awards in the military and paramilitary forces of Nazi Germany during World War II. The Knight's Cross of the Iron Cross was awarded for a wide range of reasons and across all ranks, from a senior commander for skilled leadership of his troops in battle to a low-ranking soldier for a single act of extreme gallantry. A total of 7,321 awards were made between its first presentation on 30 September 1939 and its last bestowal on 17 June 1945. This number is based on the analysis and acceptance of the order commission of the Association of Knight's Cross Recipients (AKCR). Presentations were made to members of the three military branches of the Wehrmacht—the Heer (Army), Kriegsmarine (Navy) and Luftwaffe (Air Force)—as well as the Waffen-SS, the Reichsarbeitsdienst (RAD—Reich Labour Service) and the Volkssturm (German national militia). There were also 43 recipients in the military forces of allies of the Third Reich.

These recipients are listed in the 1986 edition of Walther-Peer Fellgiebel's book, Die Träger des Ritterkreuzes des Eisernen Kreuzes 1939–1945 — The Bearers of the Knight's Cross of the Iron Cross 1939–1945. Fellgiebel was the former chairman and head of the order commission of the AKCR. In 1996, the second edition of this book was published with an addendum delisting 11 of these original recipients. Author Veit Scherzer has cast doubt on a further 193 of these listings. The majority of the disputed recipients had received the award in 1945, when the deteriorating situation of Germany in the final days of World War II in Europe left a number of nominations incomplete and pending in various stages of the approval process.

Listed here are the 82 Knight's Cross recipients of the Wehrmacht and Waffen-SS whose last name starts with "C". The recipients are initially ordered alphabetically by last name. The rank listed is the recipient's rank at the time the Knight's Cross was awarded.
