The Armed Forces of Armenia (Armenian: Հայաստանի զինված ուժեր, romanized: Hayastani zinvats uzher), sometimes referred to as the Armenian Army (Armenian: Հայկական Բանակ, romanized: Haykakan Banak), is the national military of Armenia. It consists of personnel branches under the General Staff of the Armenian Armed Forces, which can be divided into two general branches: the Ground Forces, and the Air Force and Air Defense Forces. Though it was partially formed out of the former Soviet Army forces stationed in the Armenian SSR (mostly units of the 7th Guards Army of the Transcaucasian Military District), the military of Armenia can be traced back to the founding of the First Republic of Armenia in 1918. Being a landlocked country, Armenia has no navy.

The Commander-in-Chief of the military is the Prime Minister of Armenia, Nikol Pashinyan. The Ministry of Defence is in charge of political leadership, headed by Vagharshak Harutiunyan, while military command remains in the hands of the general staff, headed by the Chief of Staff, who is Lieutenant-General Artak Davtyan. Border guards subject to the Ministry of Defence until 2001, patrol Armenia's borders with Georgia and Azerbaijan, while Russian troops continue to monitor its borders with Iran and Turkey. Since 2002, Armenia has been a member of the Collective Security Treaty Organization. Armenia signed a military cooperation plan with Lebanon on 27 November 2015.
