"Liebster Gott, wann werd ich sterben" ("Dearest God, when will I die") is a Lutheran hymn which Caspar Neumann, an evangelical theologian from Breslau, wrote around 1690. The topic of the hymn, which has five stanzas of eight lines, is a reflection on death. An elaborate analysis of the hymn's content was published in 1749. A few text variants of the hymn originated in the 18th century. Neumann's text is usually sung to the hymn tune of "Freu dich sehr o meine Seele".
