Sir Hubert de la Poer Gough (August 12, 1870–1963) was a British World War I general who commanded the British Fifth Army from 1916 to 1918.
Gough was a cavalry officer who, as a favourite of the British Commander-in-Chief, General Sir Douglas Haig, experienced a meteoric rise through the ranks during the war. At the outbreak of war in August 1914, Gough was commanding a brigade and later commanded the 7th Division, known as "Gough's Mobile Army". By the time of the Battle of Loos in September 1915 he was commanding I Corps and at the start of the Battle of the Somme in July 1916 Gough was in charge of the Reserve Army, despite only being a lieutenant general. At the end of October 1916, Gough's Reserve Army was renamed the Fifth Army.
It was Gough's Fifth Army that bore the brunt of the German Operation Michael offensive on 21 March 1918 and the failure of his army to hold the line and stem the German advance led to his dismissal.
