"I Sing a Song of the Saints of God" is a Christian hymn written in Britain by Lesbia Scott and first published in 1929.

She wrote both the words and the tunes and in 1929 published them in a collection, Everyday Hymns For Little Children,[1] which she also illustrated.

Each hymn was devised for a different occasion, and one of them, "Saints' Days", found its way to the United States and was set to a new tune ("Grand Isle") composed especially for it by retired Episcopal priest John H. Hopkins, Jr. (1861-1945)[2] who was the son of the Rev.

It has been retained in the subsequent The Hymnal 1982 as Hymn #293, after its proposed removal for "lack of theological profundity" that prompted a letter-writing campaign to keep it.

The hymn remains a popular favourite with American churchgoers who have grown up with it.
