Nathaniel Bright Emerson (July 1, 1839 Waialua, Oahu – July 16, 1915, at sea) was a medical physician and author of Hawaiian mythology. He was the son of Protestant missionaries John S. Emerson and Ursula Newell Emerson, and father of artist Arthur Webster Emerson. Emerson was an historian and writer of Hawaiian mythology. One of his efforts was the translation into English of David Malo's work on Hawaiian lore and customs. In 1909, the Bureau of American Ethnology published his book, Unwritten Literature of Hawaii, and his last work, Pele and Hiiaka, was published in 1915.
