Anti-Americanism is a term that can describe several sentiments and positions including opposition to, fear of, distrust of, prejudice against or hatred toward the United States, its government, its foreign policy, or Americans in general. Anti-Americanism can be contrasted with pro-Americanism, which refers to support, love, or admiration for the United States.

Stereotypes of American people can today be found in virtually all cultures. They often manifest in America's own television and in the media's portrayal of the United States as seen in other countries, but can also be spread by literature, art, and public opinion. Not all of the stereotypes are equally popular, nor are they all restricted to Americans; and although most can be considered negative, a few assign neutral, positive or admiring qualities to the stereotypical U.S. citizen. Many of the ethnic stereotypes collide with otherwise unrelated political anti-Americanism.
