Robert Ranke Graves (24 July 1895 – 7 December 1985) was an English poet, translator and novelist. During his long life, he produced more than 140 works. He was the son of the Anglo-Irish writer Alfred Perceval Graves and Amalie von Ranke, a niece of the famous German historian Leopold von Ranke. He was the brother of the author Charles Patrick Graves and half-brother of Philip Graves.

Graves considered himself a poet first and foremost. His poems, together with his translations and innovative interpretations of the Greek Myths, his memoir of the First World war, Good-bye to All That, and his historical study of poetic inspiration, The White Goddess, have never been out of print.

He earned his living from writing, particularly popular historical novels such as I, Claudius, King Jesus, The Golden Fleece, and Count Belisarius. He also was a prominent translator of Classical Latin and Ancient Greek texts; his versions of The Twelve Caesars and The Golden Ass remain popular today for their clarity and entertaining style. Graves was awarded the 1934 James Tait Black Memorial Prize for both I, Claudius and Claudius the God.
