The City and Borough of Yakutat (, ; Tlingit: "Yaakwdáat"; ) is a borough in the U.S. state of Alaska and was the name of a former city within it. The name is Tlingit, "Yaakwdáat" ("the place where canoes rest") but it originally derives from an Eyak name "diyaʼqudaʼt" and was influenced by the Tlingit word "yaakw" ("canoe, boat"). The borough covers an area about six times the size of the U.S. state of Rhode Island, making it one of the largest counties (or county equivalents) in the United States. As of the 2010 census, the population was 662, making it the ninth-least populous county nationwide down from 680 in 2000.
