Arthur Bliss Lane (16 June 1894 – 12 August 1956) was a United States diplomat who served in Latin America and Europe.

While serving there he met with General Somoza while the President of Nicaragua Sacasa held talks with rebel leader Augusto César Sandino.

Lane spent the next two years trying to reconcile Somoza and Sacasa, leaving the country before the next election as the U.S. adopted a more non-interventionist policy.

While in Poland, Lane resigned his post on February 24, 1947, in protest of the takeover of the country by the Communist puppet regime,[2] and wrote a book detailing 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.

The Yalta Conference was the final death blow to Poland's hopes for independence and for a democratic form of government, according to Lane.
