George Angus Garrett (August 5, 1888 – September 29, 1971) was an American investment banker and diplomat.

In April 1947, Garrett was appointed minister to Ireland by President Harry S. Truman,[4] and became the last US chief of mission in Ireland with the formal title of Envoy Extraordinary and Minister Plenipotentiary.

[2] In 1950, the post was raised to the level of ambassador, and Garrett was again appointed by Truman,[5] becoming the first US chief of mission in Ireland with the formal title of Ambassador Extraordinary and Plenipotentiary.

[2] Although Garrett's relations with Ireland's Taoiseach (prime minister) Éamon de Valera were not unfriendly, he made no secret of his pleasure when de Valera was replaced in 1948 by John A. Costello, for whom Garrett had the greatest admiration, and whom he thought a more reliable friend to the United States.

[6] Garrett died on September 29, 1971,[7] and was interred at the Washington National Cathedral.
