Bruno Zwintscher (15 May 1838 – 4 March 1905) was a German piano educator.
Born in Ziegenhain (now part of Nossen) in the Kingdom of Saxony, Zwintscher attended the Dresdener Kreuzschule before he became a student of Louis Plaidy at the University of Music and Theatre Leipzig in 1856.
From 1875 to 1896, Zwintscher himself worked as a piano teacher at this conservatory.
Otto, born from Zwintscher's marriage to Frieda, had three sons: the philologist Arthur (1867–1937), the painter Oskar (1870–1916) and the pianist Rudolf (1871–1946).
Zwintscher died in Oberlößnitz [de] near Radebeul at the age of 64.
