Leutnant Hartmuth Baldamus (first name sometimes rendered Hartmut) (10 August 1891 – 14 April 1917) was a German World War I flying ace credited with 18 aerial victories.

Ranked as a Gefreiter, he flew a two-seater reconnaissance airplane for Feldflieger Abteilung 20 (Field Flier Detachment 20) beginning 29 March 1915.

[1][2] The requirement for winning the Pour le Merite had been set at eight victories for the very earliest German aces, the so-called Fokker Scourge.

[1][note 1] Baldamus resumed scoring on 23 January 1917, and steadily achieved more single victories, reaching 17 on 12 April 1917.

Two days later, at 1140 hours, Hartmut Baldamus slammed into a midair collision with the French Nieuport 17 serial 2539 of Escadrille N37 piloted by Caporal Simon.
