Venezuela came in a close second for having the most patriotism, according to the report from the National Opinion Research Centre at the University of Chicago.
People rated how proud they were of their countries in areas such as political influence, economic success, sports and history.
They survey ranked 34 countries, mostly in Europe and the Americas, with several Asian countries represented. Only Israel was included from Middle Eastern countries.
“The two things (Americans) rank high on are what we think of as the political or power dimension,” said Tom Smith, who wrote the report.
“Given that we’re the one world superpower, it’s not that surprising,” said Mr Smith, who directs the General Social Survey at the university’s research centre.
Patriotism is mostly a “New World” concept, the survey said. Ex-colonies and newer nations were more likely to rank high on the list, while Western European, East Asian and former Socialist countries usually ranked near the middle or bottom.
The report was based on a survey in 34 countries conducted by the International Social Survey Program.
People rated how proud they were of their countries in 10 areas: political influence, social security, the way their democracy works, economic success, science and technology, sports, arts and literature, military, history, and fair treatment of all groups in society.
The US ranked highest overall and in five categories: pride in its democracy, political influence, economy, science and military.
Venezuela came in second by ranking highest in four categories: sports, arts and literature, history, and fair treatment of all groups in society.
Eric Wingerter, a Washington DC-based spokesman for the Venezuelan government, said the country previously imported much of its television programming, movies and pop music from the US, but that has changed under President Hugo Chavez’s leadership.
Many Venezuelans say Chavez has helped create a new sense of national pride, he said.
“There’s been a real emphasis on rediscovering what it means to be Venezuelan,” he said.
The debate in Venezuela over Chavez, who makes headlines for nationalistic, anti-US rhetoric, might account for the country’s
No. 2 ranking, Smith said.
“We looked at, ‘Well, is it just the Chavez support, or is it the image of the country?’ and they’re actually both high,” Mr Smith said.
Cultural differences might explain lower rankings for the three Asian countries on the list – Japan (18th), Taiwan (29th), and Korea (31), Mr Smith said.
“It is both bad luck and poor manners to be boastful about things there,” Mr Smith said.
Countries that were part of the former Soviet Union or in the former Eastern Bloc ranked lower because they are still struggling to find new national identities. Hungary was the highest Eastern European country on the list at 21.
Here is how the countries ranked:
-1. United States
-4. South Africa
-9. New Zealand
-11. Great Britain
-27. Germany (West)
-28. Czech Republic
-34. Germany (East)
