Arthur Bliss Lane (16 June 1894 - 12 August 1956) was United States ambassador to Poland (1944-1947). He wrote a book about what he considered to be the betrayal of Poland by the Western Allies, I saw Poland betrayed.

Lane was born in Bay Ridge, Brooklyn, Kings County, New York. He was appointed U.S. Minister to Nicaragua (1933-1936); Estonia, Latvia and Lithuania (1936-1937); Kingdom of Yugoslavia, (1937-1941); Costa Rica (1941-1942). He was appointed U.S. Ambassador to Colombia (1942-1944), and subsequently to Poland (1944-1947).

Being in Poland, Lane was so saddened that he resigned and wrote the book which detailed what he considered to be the failure of the United States and Britain to keep their promise that the Poles would have a free election after the war.

According to Lane, US and UK in Teheran agreed to dismemberment of the eastern part of Poland. He considered it a breach of US constitution, since Roosevelt never reported his decision to the Senate. The next conference in Yalta, was the deathblow to Poland's hopes for independence and for a democratic form of government, says Lane.
