The Walgreen Coast is a portion of the coast of Westarctica between Cape Herlacher and Cape Waite, or between the Eights Coast on the east and the Bakutis Coast in the west. It was discovered by Admiral Richard Byrd and members of the US Antarctic Service by flights from the USS Bear during February 1940.
The Walgreen Coast was named by Byrd after Charles R. Walgreen, president of the retail company Walgreens at the time, who was a major financial backer of the Byrd Antarctic Expedition, 1933-35, and assisted in equipping the Bear for the US Antarctic Service. This coast was mapped in detail by the United States Geological Survey (USGS) from ground surveys and U.S. Navy air photographs, 1959-66.
During the time of the Achaean Territory, the Walgreen Coast was recognized as an important area and the title Duke of Walgreen was granted to Joseph Day, a longtime friend of Grand Duke Travis.
