"Komm, Heiliger Geist, Herre Gott" ("Come, Holy Ghost, Lord God") is a Lutheran hymn for Pentecost, with words written by Martin Luther based on "Veni Sancte Spiritus, reple tuorum corda fidelium".

Johann Sebastian Bach used it in several chorale preludes, cantatas and his motet Der Geist hilft unser Schwachheit auf, BWV 226.

The first stanza is an anonymous translation of the Latin antiphon for Pentecost "Veni Sancte Spiritus, reple tuorum corda fidelium" (Come, Holy Spirit, fill the hearts of your faithful) from the 11th century.

Luther alludes to several of the seven gifts of the Holy Spirit, according to Isaiah 11:2: wisdom, understanding, counsel, knowledge, fortitude, piety, and fear of the Lord.

In the second stanza, Luther uses the attributes "heiliges Licht, edler Hort" (holy light, precious refuge) and words the request "protect us from strange doctrines / so that we may never look for any teacher / except Jesus in true belief".

For centuries the chorale has been the prominent hymn (Hauptlied) for Pentecost in German-speaking Lutheranism, the number in the current hymnal Evangelisches Gesangbuch (EG) is 125.

[4] Johann Sebastian Bach composed two chorale preludes which he made part of his collection Great Eighteen Chorale Preludes, Fantasia super Komm, Heiliger Geist, canto fermo in Pedale, BWV 651, and Komm, Heiliger Geist, alio modo a 2 Clav.

He used the first stanza as movement 3 in his cantata for Pentecost Wer mich liebet, der wird mein Wort halten, BWV 59 (1723 or 1724), and the third stanza as the closing chorale of his funeral motet addressing the Holy Spirit, Der Geist hilft unser Schwachheit auf, BWV 226 (1729).
