The Romanian Land Forces (Romanian: Forţele Terestre Române) is the army of Romania, and the main component of the Romanian Armed Forces. In recent years, full professionalisation and a major equipment overhaul have transformed the nature of the force.^{[citation needed]}

The Romanian Land Forces were founded on 24 November [O.S. 12 November] 1859. They participated in World War I, together with the Russian Empire forces in actions against the Central Powers and, despite initial setbacks, won the decisive battles of Mărăşti and Mărăşeşti. During most of World War II (until August 23, 1944) Romanian forces supported the Axis powers, fighting against the Soviet Union on the Eastern Front. From August 1944 until the end of the war, Romania fought against Germany under the control of the Soviet Union. When the communists seized power after the Second World War, the army underwent reorganisation and sovietization.

Following the 1989 revolution, due to shortage of funds, many units were disbanded and much equipment was phased out. Likewise, Romanian military capability declined because of a lack of fuel as well as training. However, since the late 1990s, a number of positive changes have come about and the level of combat readiness is growing greatly; since 1996, the military budget has grown more than four times - rising from 636 million dollars to 2.8 billion dollars in 2007. Conscription has been abolished and professionalisation has been completed. The full modernisation of equipment ended at the end of 2007.

An army (from Latin arma “arms, weapons” via Old French armée, “armed” (feminine)), in the broadest sense, is the land-based military branch, service branch or armed service of a nation or state. It may also include other branches of the military such as the air force via means of aviation corps. Within a national military force, the word army may also mean a field army an army composed of full-time career soldiers who 'stand over', in other words, who do not disband during times of peace. They differ from army reserves who are activated only during such times as war or natural disasters.

In several countries, the army is officially called the Land Army to differentiate it from an air force called the Air Army, notably France. In such countries, the word "army" on its own retains its connotation of a land force in common usage. The current largest army in the world, by number of active troops, is the People's Liberation Army of China with 2,250,000 active troops and 800,000 reserve personnel followed by the Indian Army with 1,325,000 active troops and 2,142,821 reserve personnel.
