Irwyn Ranald Walters (6 December 1902 – 21 November 1992) was a Welsh musician, conductor and administrator.
In his youth, Walters' musical tutorship came from conductor Gwilym R. Jones, and David Vaughan Thomas (1873-1934).
Irwyn's education took place at Amman Valley County School and Aberystwyth.
He remained an active musician throughout his life, even during World War II, when he organised various concerts across Wales.
Irwyn Walters founded the National Youth Orchestra of Wales in 1945, primarily in response to the high demand for orchestral education being provided in England, and served as its director for a time.
