Adalbert Dani von Gyarmata und Magyar-Cséke (also sometimes spelled Magyarcseke; 26 May 1868—14 April 1920) was an officer of the Austro-Hungarian Army who served in World War I, holding a number of senior positions, including chief of staff of VI Corps, Army Group Tersztyanszky, and the 3rd Army.
Before the conflict began, he had worked in Russia, China, and Japan as a military attaché, becoming an observer during the Russo-Japanese War.
It was during that time that von Gyarmata became acquainted with John Pershing, who went on to command the American Expeditionary Force in Europe during the war.
