The Egyptian Army () or Egyptian Ground Forces () is the land warfare branch of the Egyptian Armed Forces. It is the largest service branch of the Egyptian Armed Forces. The modern army was established during the reign of Muhammad Ali Pasha (1805–1849), widely considered to be the "founder of modern Egypt". Its most significant engagements in the 20th century were in Egypt's five wars with the State of Israel (in 1948, 1956, 1967, 1967–1970, and 1973), one of which, the Suez Crisis of 1956, also saw it do combat with the armies of the United Kingdom and France. The Egyptian army was also engaged heavily in the protracted North Yemen Civil War, and the brief Egyptian–Libyan War in July 1977. Its last major engagement was Operation Desert Storm, the liberation of Kuwait from Iraqi occupation in 1991, in which the Egyptian army constituted the second-largest contingent of the allied forces. As of 2021, the army has an estimated strength of 310,000 of which approximately 90,000–120,000 are professionals and the rest conscripts. There exists an additional 375,000 reservists.

During the intermediate periods between kingdoms government control was in the hands of the various nomes (provinces within Egypt) and various foreigners. This circumstance set the stage for many of Egypt's military conquests. They weakened their enemies by using small projectile weapons, like bows and arrows. They also had chariots which they used to charge at the enemy. The arid plains and deserts surrounding Egypt were inhabited by nomadic tribes who occasionally tried to raid or settle in the fertile Nile River valley. Nevertheless, the great expanses of the desert formed a barrier that protected the river valley and was almost impossible for massive armies to cross. The Egyptians built fortresses and outposts along the borders east and west of the Nile Delta, in the Eastern Desert, and in Nubia to the south. Small garrisons could prevent minor incursions, but if a large force was detected a message was sent for the main army corps. Most Egyptian cities lacked city walls and other defenses.
