The Ottoman Seventh Army was a large military formation of the Ottoman Empire in the late 19th and early 20th centuries. Although designated as an army, at least by 1918, it was only of corps strength. The Seventh Army was established in 1877 for service in Arabia and the Yemen. By 1908 it consisted of the 13th and 14th infantry divisions, one cavalry regiment and one artillery regiment and they were involved in combatting insurgent tribesmen in the Yemen.
