The United States Soccer Federation (USSF), commonly referred to as U.S. Soccer, is the official governing body of the sport of Association Football primarily known as soccer in the United States. Its headquarters are located in Chicago, Illinois. It is a member of FIFA and is responsible for governing amateur and professional soccer, including the men's, women's, youth, futsal and Paralympic national teams. U.S. Soccer is also responsible for sanctioning referees and soccer tournaments for most soccer leagues in the United States.

U.S. Soccer was originally known as the United States of America Football Association. It formed on April 5, 1913 and on August 15 of that year was accepted as one of the earliest member organizations of FIFA and the first from North and Central America. The affiliation was temporary and at the following year's FIFA Congress in 1914, the USFA, as it was abbreviated at the time, was accepted as a full FIFA member along with the Spanish federation. The governing body of the sport in the United States did not have the word soccer in its name until 1945, when it became the United States Soccer Football Association. It did not drop the word football from its name until 1974, when it became the United States Soccer Federation.

The United States of America (commonly abbreviated to the United States, the U.S., the USA, America, and the States) is a federal constitutional republic comprising fifty states and a federal district. The country is situated mostly in central North America, where its forty-eight contiguous states and Washington, D.C., the capital district, lie between the Pacific and Atlantic Oceans, bordered by Canada to the north and Mexico to the south. The state of Alaska is in the northwest of the continent, with Canada to the east and Russia to the west, across the Bering Strait. The state of Hawaii is an archipelago in the mid-Pacific. The country also possesses several territories in the Pacific and Caribbean.

At 3.79 million square miles (9.83 million km²) and with over 312 million people, the United States is the third or fourth largest country by total area, and the third largest by both land area and population. It is one of the world's most ethnically diverse and multicultural nations, the product of large-scale immigration from many countries. The U.S. economy is the world's largest national economy, with an estimated 2011 GDP of $15.1 trillion (22% of nominal global GDP and over 19% of global GDP at purchasing-power parity). Per capita income is the world's sixth-highest.
