Armenians have lived in Lebanon for centuries. According to Minority Rights Group International, there are 156,000 Armenians in Lebanon, around 4% of the population. Prior to the Lebanese Civil War, the number was higher, but the community lost a portion of its population to emigration.

Armenians are an ethnic group and nation native to the Armenian highlands of West Asia. Armenians constitute the main population of the Republic of Armenia and constituted the main population of the breakaway Republic of Artsakh until the 2023 Azerbaijani offensive in Nagorno-Karabakh and the subsequent flight of Nagorno-Karabakh Armenians. There is a wide-ranging diaspora of around five million people of full or partial Armenian ancestry living outside modern Armenia. The largest Armenian populations today exist in Russia, the United States, France, Georgia, Iran, Germany, Ukraine, Lebanon, Brazil, Argentina, Syria, and Turkey. The present-day Armenian diaspora was formed mainly as a result of the Armenian genocide with the exceptions of Iran, former Soviet states, and parts of the Levant.
