Nun komm, der Heiden Heiland (Now come, Saviour of the heathens) is a Lutheran chorale with words by Martin Luther, based on Veni redemptor gentium by Ambrose. It was printed in the Erfurt Enchiridion of 1524. The chorale was used as the prominent hymn for the first Sunday of Advent for centuries. It was used widely in organ settings by Protestant baroque composers.
