Diana Rowan (born 26 January 1971 in Dublin, Ireland) is an Irish harpist and pianist.
Rowan was born to Belfast-bred parents while they were students at Trinity College, Dublin.
Upon graduation, her father John Rowan joined the Irish Foreign Service as a diplomat.
Diana was noticed by Robert Redaelli, the head of the music conservatory she attended in Brussels, Belgium, and he would occasionally teach her himself in addition to her regular teacher Greek-born Mina Papamanolis.
Rowan's work is influenced primarily by Bach, Debussy, Poulenc, Bartók, and Celtic, Balkan, Middle Eastern and Hindustani styles.
