The Turkish Land Forces, or Turkish Army, is the main branch of the Turkish Armed Forces responsible for land-based military operations. The army was formed on November 8, 1920, after the collapse of the Ottoman Empire. Significant campaigns since the foundation of the army include suppression of rebellions in Southeast Anatolia and East Anatolia from the 1920s to the present day, combat in the Korean War, the 1974 Turkish invasion of Cyprus and the current Turkish involvement in the Syrian Civil War, as well as its NATO alliance against the USSR during the Cold War. The army holds the preeminent place within the armed forces. It is customary for the Chief of the General Staff of the Turkish Armed Forces to have been the Commander of the Turkish Land Forces prior to his appointment as Turkey's senior ranking officer.

Turkey's involvement in the Syrian Civil War began diplomatically and later escalated militarily. Initially, Turkey condemned the Syrian government at the outbreak of civil unrest in Syria during the spring of 2011; the Turkish government's involvement gradually evolved into military assistance for the Free Syrian Army in July 2011, border clashes in 2012, and direct military interventions in 2016–17, in 2018, in 2019, 2020, and in 2022. The military operations have resulted in the Turkish occupation of northern Syria since August 2016.
