Island of the Blue Dolphins is a 1960 children's novel by American writer Scott O'Dell, which tells the story of a girl named Karana, who is stranded alone for years on an island off the California coast. It is based on the true story of Juana Maria, a Nicoleño Native American left alone for 18 years on San Nicolas Island during the 19th century.

Juana Maria, better known to history as the Lone Woman of San Nicolas Island, was a Native Californian woman who was the last surviving member of her tribe, the Nicoleño. She lived alone on San Nicolas Island off the coast of Alta California from 1835 until her removal from the island in 1853. Scott O'Dell's award-winning children's novel Island of the Blue Dolphins (1960) was inspired by her story. She was the last native speaker of the Nicoleño language.
