Twelve United States presidents have made presidential visits to the United Kingdom and Ireland. The first visit by an incumbent president to the United Kingdom was made in December 1918 by Woodrow Wilson, and was an offshoot of American diplomatic interactions with the Principal Allied Powers at the conclusion of World War I prior to the Paris Peace Conference. The first visit by an incumbent president to Ireland was made in June 1963 by John F. Kennedy. To date, 39 visits have been made to the United Kingdom and eleven to Ireland.
