"This Little Girl of Mine" is a rhythm and blues single written and released as a single by Ray Charles in 1955 on the Atlantic label. "This Little Girl of Mine" played off "This Little Light of Mine", much like the previous "I Got a Woman" and the later "Hallelujah I Love Her So" played off other classic gospel hymns. And much like those songs, replaced sacred lyrics with secular blues lyrics with doo-wop call and response harmonies. The song was the B-side to Charles' number-one R&B single, "A Fool for You", and was a charted hit on its own, peaking at number nine on the chart.
