Armenian Americans (Armenian: ամերիկահայեր, romanized: amerikahayer) are citizens or residents of the United States who have total or partial Armenian ancestry. They form the second largest community of the Armenian diaspora after Armenians in Russia. The first major wave of Armenian immigration to the United States took place in the late 19th and early 20th centuries. Thousands of Armenians settled in the United States following the Hamidian massacres of the mid-1890s, the Adana massacre of 1909, and the Armenian genocide of 1915–1918 in the Ottoman Empire. Since the 1950s many Armenians from the Middle East (especially from Lebanon, Syria, Iran, Iraq, Egypt, and Turkey) migrated to the United States as a result of political instability in the region. It accelerated in the late 1980s and has continued after the dissolution of the Soviet Union in 1991 due to socio-economic and political reasons. The Los Angeles area has the largest Armenian population in the United States.
The 2020 United States census reported that 519,001 Americans held full or partial Armenian roots either alone or combined with another ancestral origin. Various organizations and media criticize these numbers as an underestimate, proposing 800,000 to 1,500,000 Armenian Americans instead. The highest concentration of Americans of Armenian descent is in the Greater Los Angeles area, where 166,498 people have identified themselves as Armenian to the 2000 census, comprising over 40% of the 385,488 people who identified Armenian origins in the United States at the time. The city of Glendale, in the Los Angeles metropolitan area, is widely thought to be the center of Armenian American life (although many Armenians live in the aptly named "Little Armenia" neighborhood of Los Angeles).
