Freue dich, erlöste Schar, BWV 30.2, BWV 30, is a church cantata by Johann Sebastian Bach. It is one of his later realisations in the genre: he composed it for the Feast of John the Baptist in 1738, and based its music largely on Angenehmes Wiederau, a secular cantata which he had composed a year earlier. Christian Friedrich Henrici (Picander), the librettist of the secular model of the cantata, is likely also the author of the sacred cantata's version of the text.
