List of ambassadors of the United States to Czechoslovakia

Following the dissolution of the Austro-Hungarian Empire in 1918 at the end of World War I, the Czechs and Slovaks united to form the new nation of Czechoslovakia. The United States recognized Czechoslovakia and commissioned its first ambassador on April 23, 1919.

Nazi Germany invaded Czechoslovakia in March 1939, establishing a German "protectorate", the Protectorate of Bohemia and Moravia. By this time, Slovakia had already declared independence and had become a puppet state of Germany, the Slovak Republic. German forces occupied Prague on March 15, 1939. The U.S. embassy was closed on March 21, 1939 and the ambassador left his post on April 6, 1939.

During World War II the U.S. maintained diplomatic relations with the Czechoslovak government-in-exile in London. Ambassador Anthony J. Biddle, Jr. established an embassy in London on September 17, 1941 and the embassy was maintained until the end of World War II in Europe. Following the war the embassy in Prague was reopened on May 29, 1945.

In June 1992, the Slovak parliament voted to declare sovereignty and the Czech-Slovak federation dissolved peacefully on January 1, 1993. The United States recognized the Czech Republic and Slovakia as independent nations and moved to establish diplomatic relations. The previous ambassador to Czechoslovakia, Adrian A. Basora, continued as the ambassador to the Czech Republic. Paul Hacker, the incumbent U.S. consul general, served as the first chargé d'affaires of the U.S. Embassy in Slovakia (January 1 to July 7, 1993), followed by Eleanor Sutter. In November 1993, Theodore E. Russell, former deputy chief of mission in Prague, became the first U.S. ambassador to Slovakia.
