Greece–United States relations

Due to the strong historical, political, cultural and religious ties between them, Greece and the United States today enjoy excellent diplomatic relations and consider each other an ally. Today Greece is one of the United States's closest allies.

Diplomatic relations between Greece and the United States were established in the 1830s after the Greek War of Independence. Greece and the United States have long-standing historical, political, and cultural ties based on a common western heritage, and participation as Allies during World War I, World War II, the Cold War and the War on Terror. The governments of the two countries cooperate closely in the areas of finance, energy, commerce, technology, academics, sciences, judiciary, intelligence and military, as well as through many multilateral organizations such as the Organization for Security and Co-operation in Europe (OSCE), the Organisation for Economic Co-operation and Development (OECD), the North Atlantic Treaty Organization (NATO), and the United Nations; they are both founding members of the latter.

The United States is the largest foreign investor in Greece; direct U.S. foreign investment in Greece was about $4.5 billion in 2006.

Americans are consistently well liked in Greece. In 2005 67% of Greeks viewed Americans favorably, in 2016 the figure was 66%.
