Michael Mietke (c. 1656/1671 – 1719) was a German harpsichord and harp maker.
He succeeded Christoph Werner in 1707 as official maker to the court.
[2] Three of his harpsichords survive: A plain single-manual instrument, preserved Hudiksvall, Sweden, is signed 'Berlin, 1710'.
[3] One is a single-manual, which belonged personally to Queen Sophie Charlotte, and the other a double-manual.
Both are lavishly decorated by the court decorator Gerard Dagly: the single manual instrument, covered with gilded chinoiserie on a porcelain white background, earning the instrument the affectionate modern nickname "The White Mietke", while the double manual instrument is in similar style, but on a black background and thus often referred to as "The Black Mietke".
