Icelandic Americans are Americans of Icelandic descent or Iceland-born people who reside in the United States. Icelandic immigrants came to the United States primarily in the latter half of the 19th century and after World War II. There are more than 40,000 Icelandic Americans according to the 2000 U.S. census, and most live in the Upper Midwest. The United States is home to the second largest Icelandic diaspora community in the world after Canada.
