Eluned Morgan (20 March 1870 – 29 December 1938) was a Welsh-language author from Patagonia. She was raised in Y Wladfa, a Welsh colony in Patagonia, and was taught to speak both Welsh and Spanish. Her father eventually enrolled her in Dr Williams' School in Wales, where she had to learn the English language. She led student protests against the school's English-only policy, which prohibited the use of Welsh by its students.
As a writer, Morgan is primarily remembered for two travel books which described journeys to Patagonia and to the Andes. Her book Dringo'r Andes also covered in detail the relations between different ethnic groups. Otherwise, Morgan is remembered for writing a history of the Incas.
After spending a few decades in Wales, Morgan returned to Patagonia in 1918. She spend the rest of her life there.
