Hungarian Americans are Americans of Hungarian descent. The U.S. Census Bureau has estimated that there are approximately 1.396 million Americans of Hungarian descent as of 2018. The total number of people with ethnic Hungarian background is estimated to be around 4 million. The largest concentration is in the Greater Cleveland Metropolitan Area in Northeast Ohio. At one time, the presence of Hungarians within Cleveland proper was so great that the city was known as the "American Debrecen," with one of the highest concentrations of Hungarians in the world.
