Greek Americans (Greek: Ελληνοαμερικανοί, Ellinoamerikanoi) are Americans of full or partial Greek ancestry. The United States is home to the largest Greek community outside of Greece, ahead of Australia, Cyprus, Albania, Canada, Germany, and the United Kingdom.
More than 1.4 million Americans are of Greek descent. In 2010, 321,444 people older than five spoke Greek at home. Greek Americans have the highest concentrations in the New York City, Boston, and Chicago regions, but have settled in major metropolitan areas across the United States. In 2000, Tarpon Springs, Florida was home to the highest per capita representation of Greek Americans in the country (25%).
