Wilhelm Heye (31 January 1869 – 11 March 1947) was a Prussian and German officer who rose to the rank of Generaloberst and became Chief of the Army Command within the Ministry of the Reichswehr in the Weimar Republic.

[2] Heye served from 27 January 1906 to 31 March 1908 in the Schutztruppe in German South West Africa, participating in the Herero Wars as a staff officer.

[1][2] On 7 September 1918, Heye was transferred to the general staff of the field army (Generalstab des Feldheeres) and named chief of the operations section (Operationsabteilung) in the Supreme Army Command (Oberste Heeresleitung), serving under Paul von Hindenburg and Erich Ludendorff, as well as Ludendorff's successor Wilhelm Groener.

[1][2] After the Armistice ending World War I, Heye participated in the defense of Germany's post-war eastern frontier (Grenzschutz Ost) as (from 26 April 1919) chief of the general staff of the Army High Command "Border Protection North (Armeeoberkommando Grenzschutz Nord) in East Prussia.

[2] He was the successor to Hans von Seeckt, with whom Heye's military career in the subsequent years would remain closely connected.

On 1 October 1919, Heye became chief of staff of the Troop Office (Truppenamt) in the Ministry of the Reichswehr in Berlin.

During his tenure, the Heeresleitung lost much of the political influence it had under Seeckt, while the authority of the Ministry of the Reichswehr increased, principally under Wilhelm Groener and his protegé Kurt von Schleicher.

[1][2] Generaloberst Heye was placed "zur Verfügung des Heeres" (at the disposal of the army) on 1 November 1938 but was not called up during World War II.
