Latin America–United States relations

Historically speaking, bilateral relations between the various countries of Latin America and the United States of America have been multifaceted and complex, at times defined by strong regional cooperation and at others filled with economic and political tension and rivalry. Although relations between the U.S. government and most of Latin America were limited prior to the late 1800s, for most of the past century, the United States has unofficially regarded parts of Latin America as within its sphere of influence, and for much of the Cold War (1947–1991), actively vied with the Soviet Union for influence in the Western Hemisphere.

Today, the ties between the United States and most of Latin America are generally cordial, but there remain areas of tension between the two sides. Latin America is the largest foreign supplier of oil to the United States and its fastest-growing trading partner, as well as the largest source of illegal drugs and immigration, both documented and otherwise, all of which underline the continually evolving relationship between the region and country.
