The United States Ambassador to Saint Kitts and Nevis (or, prior to 3 August 1988, to Saint Christopher and Nevis) is the official representative of the government of the United States to the government of Saint Kitts and Nevis. The current Ambassador is Mary Martin Ourisman who was appointed by U.S. President George W. Bush on 15 September 2006. Ourisman is also concurrently the ambassador to Antigua and Barbuda, Barbados, Dominica, Grenada, St. Lucia, and St. Vincent and the Grenadines.
The United States established diplomatic relations with Saint Christopher and Nevis on 20 September 1983, but no U.S. mission has ever been established at Basseterre. After 25 June 1988, all relations were handled by the Embassy at St. John's, Antigua and Barbuda. When that Embassy closed on 30 June 1994, all diplomatic functions have been handled out of the U.S. Embassy at Bridgetown, Barbados, where the U.S. Ambassador to Saint Kitts and Nevis is resident.
The following is a list of U.S. Ambassadors, or other Chiefs of Mission, to Saint Kitts and Nevis. The title given by the United States State Department to this position is currently Ambassador Extraordinary and Plenipotentiary.
