The I Cavalry Corps (German: Höhere Kavallerie-Kommando 1 / HKK 1 literally: Higher Cavalry Command 1) was a formation of the German Army in World War I. It was formed on the mobilization of the German Army in August 1914 and disbanded in March 1918.

The Corps initially served on the Western Front with the Guards and 5th Cavalry Divisions and preceded the 3rd Army. By 15 September 1914, it was assigned to 2nd Army and comprised the Guards and 2nd Cavalry Divisions. Transferred to the East on 6 November 1914 and attached to the 9th Army. By 8 February 1915, it consisted of the 6th and 9th Cavalry Divisions.

At various times, the Corps was named for its commander as Cavalry Corps Richthofen, Corps Richthofen and Army Group Richthofen.

It remained with 9th Army until 20 November 1916, when it was redesignated as 56th Corps (z.b.V.).

56th Corps (z.b.V.) was formed on 20 November 1916 by the redesignation of I Cavalry Corps. As the need for large mounted cavalry formations diminished as the war went on, the existing Cavalry Corps increasingly took on the characteristics of a normal Corps Command. This culminated in them being redesignated as "General Commands for Special Use" Generalkommandos zur besonderen Verwendung (Genkdo z.b.V.). 56th Corps was disbanded on 5 March 1918.

Initially, the Corps simply consisted of 2 Cavalry Divisions (with 3 Jäger battalions attached) without any Corps troops; in supply and administration matters, the Cavalry Divisions were entirely autonomous. The commander was only concerned with tactics and strategy, hence his title of Senior Cavalry Commander Höherer Kavallerie-Kommandeur.
