Anti-Americanism, anti-American sentiment, or sometimes Americanophobia is dislike of or opposition to the United States governmental policies of the United States, especially regarding the foreign policy, or the American people in general. 

Political scientist Brendon O'Connor of the United States Studies Centre suggests that "anti-Americanism" cannot be isolated as a consistent phenomenon and that the term originated as a rough composite of stereotypes, prejudices and criticisms evolving to more politically based criticism. French scholar Marie-France Toinet says use of the term "anti-Americanism" "is only fully justified if it implies systematic opposition – a sort of allergic reaction – to America as a whole". 

Discussions on anti-Americanism have in most cases lacked a precise explanation of what the sentiment entails (other than a general disfavor), which has led to the term being used broadly and in an impressionistic manner, resulting in the inexact impressions of the many expressions described as anti-American. William Russell Melton argues that criticism largely originates from the perception that the U.S. wants to act as a "world policeman". 

Negative views of the United States are generally strongest in the Arab world, China, former Soviet countries, certain European nations, and North Korea, and weakest in Sub-Saharan Africa and most parts of Southeast Asia.
