Eiluned Lewis (1900 – 1979) was a Welsh novelist, poet and journalist.
She was born in Newtown, Montgomeryshire in Wales. She was educated at Levana School, Wimbledon, and Westfield College London. She had a long period of work on the Sunday Times, becoming assistant editor. She wrote also for Country Life magazine, from 1944 to 1979.
She married in 1937 Graeme Hendrey and they had one daughter, Katrina. Some of her books were written with her brother Peter. She was a friend of the novelist Charles Langbridge Morgan.
She was mentioned in Nico Lleyelyn Davies' (part of the family that served as J.M. Barie's inspiration for Peter Pan) letters to Andrew Birkin that she had once been a girlfriend of his brother Michael. "Reverting for a second to Michael's "girl friends", I recommend you try to get in touch with Eiluned Lewis (author of "Dew on the Grass"). I've no idea whether she and Michael even held hands but she might well have a clue as to his feelings towards girls — and she loved JMB [James Michael Barie] and all to do with us in those far off days.
