Uns ist ein Kind geboren (Unto us a child is born), BWV 142, is a Christmas cantata formerly attributed to Johann Sebastian Bach.
 The text is based on a libretto by Erdmann Neumeister first published in 1711.
 Since the cantata was first published by the Bach-Gesellschaft in the nineteenth century, Bach scholars, including Johannes Schreyer, Arnold Schering and Alfred Dürr, have not accepted this attribution, although the identity of the original composer has not been established.
 In the late twentieth century it was withdrawn from the Neue Bach Ausgabe, replaced by a detailed historical commentary on authenticity and attribution by Andreas Glöckner.
 Because of uncertainty of attribution, it remains in Anhang II of the BWV.
 It is now considered plausible that Johann Kuhnau, Bach's predecessor as Thomaskantor in Leipzig, may have composed the cantata, as originally suggested by .
