The Partita for keyboard No. 6 in E minor, BWV 830, is a suite of seven movements written for the harpsichord by Johann Sebastian Bach. It was published in 1731 both as a separate work and as part of Bach's Clavier-Übung I.

Prior to publication, two movements of BWV 830 formed part of the first version of the sixth sonata in E minor for obbligato harpsichord and violin, BWV 1019: the Corrente as a harpsichord solo; and the Tempo di gavotta as a duo for violin and harpsichord. The surviving manuscript, largely written by Bach's nephew Johann Heinrich Bach, has been dated to 1725; the harpsichord parts for these two movements were written by Bach himself. BWV 830 is the last suite in Bach's Clavier-Übung I, the first music published by Bach within his lifetime. The partitas were initially published separately, starting in 1726; the title page of the collection of six, published together in 1731, carries the designation "Opus 1".
