David Owen (January 1712 – August 1741) was a Welsh harpist, best remembered as the composer of the popular song, "Dafydd y Garreg Wen" ("David of the White Rock"), which according to tradition Owen composed as he was dying.
Dafydd y Garreg Wen was later adapted and published by harpist Edward Jones.
David Owen was the son of Owen Humphreys of Ynyscynhaearn in Caernarfonshire (the surname "Owen" being a patronymic).
His mother's maiden name was Gwen Roberts.
He composed several well-known airs.
He was buried in the churchyard of St Cynhaiarn's Church in his home village of Ynyscynhaearn.
