Robin Ernest William Flower (1881–1946) was an English poet and scholar, a Celticist, Anglo-Saxonist and translator from the Irish language. He is commonly known in Ireland as "Bláithín" (Little Flower). He married Ida Mary Streeter.
He wrote several collections of poetry, translations of the Irish poets for the Cuala Press, and verses on Blasket Island. He first visited Blasket in 1910, at the recommendation of Carl Marstrander, his teacher at the School of Irish Learning in Dublin; he acquired there the Irish nickname Bláithín. He suggested a Norse origin for the name "Blasket". Under Flower's influence, George Derwent Thomson and Kenneth Hurlstone Jackson made scholarly visits to Blasket.
After his death his ashes were scattered on the Blasket Islands.
