List of Knight's Cross of the Iron Cross recipients (Ha–Hm)

The Knight's Cross of the Iron Cross (German: Ritterkreuz des Eisernen Kreuzes) and its variants were the highest award in the military of the Third Reich 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. The following is the complete list of all 661 Knight's Cross of the Iron Cross recipients whose last name starts with "H". Listed here are the 437 recipients whose last name is in the range "Ha–Hm". The recipients whose last name is in the range "Hn–Hz" is listed at List of Knight's Cross of the Iron Cross recipients (Hn–Hz).

The number of 437 Knight's Cross recipients whose last name starts with "Ha–Hm" is based on the analysis and acceptance of the order commission of the Association of Knight's Cross Recipients (AKCR). Author and historian Veit Scherzer has challenged the validity of 15 of these listings. Hermann Hessler, a 16th doubted recipient, is listed by the AKCR. However the AKCR themselves challenge his listing. The recipients are ordered alphabetically by last name. The rank listed is the recipient's rank at the time the Knight's Cross was awarded.

Background
The Knight's Cross of the Iron Cross and its higher grades were based on four separate enactments. The first enactment, Reichsgesetzblatt I S. 1573 of 1 September 1939 instituted the Iron Cross (Eisernes Kreuz), the Knight's Cross of the Iron Cross and the Grand Cross of the Iron Cross (Großkreuz des Eisernen Kreuzes). Article 2 of the enactment mandated that the award of a higher class be preceded by the award of all preceding classes. As the war progressed, some of the recipients of the Knight's Cross distinguished themselves further and a higher grade, the Oak Leaves to the Knight's Cross of the Iron Cross, was instituted. The Oak Leaves, as they were commonly referred to, were based on the enactment Reichsgesetzblatt I S. 849 of 3 June 1940. In 1941, two higher grades of the Knight's Cross were instituted. The enactment Reichsgesetzblatt I S. 613 of 28 September 1941 introduced the Knight's Cross of the Iron Cross with Oak Leaves and Swords (Ritterkreuz des Eisernen Kreuzes mit Eichenlaub und Schwertern) and the Knight's Cross of the Iron Cross with Oak Leaves, Swords and Diamonds (Ritterkreuz des Eisernen Kreuzes mit Eichenlaub, Schwertern und Brillanten). At the end of 1944 the final grade, the Knight's Cross of the Iron Cross with Golden Oak Leaves, Swords, and Diamonds (Ritterkreuz des Eisernen Kreuzes mit goldenem Eichenlaub, Schwertern und Brillanten), based on the enactment Reichsgesetzblatt 1945 I S. 11 of 29 December 1944, became the final variant of the Knight's Cross authorized.

Recipients
The Oberkommando der Wehrmacht (Supreme Command of the Armed Forces) kept separate Knight's Cross lists, one for each of the three military branches, Heer (Army), Kriegsmarine (Navy), Luftwaffe (Air force) and for the Waffen-SS. Within each of these lists a unique sequential number was assigned to each recipient. The same numbering paradigm was applied to the higher grades of the Knight's Cross, one list per grade. The sequential numbers greater than 843 for the Knight's Cross of the Iron Cross with Oak Leaves and 143 for the Knight's Cross of the Iron Cross with Oak Leaves and Swords are unofficial and were assigned by the Association of Knight's Cross Recipients (AKCR) and are therefore denoted in parentheses.
