Georg Eugen Krantz (13 September 1844 – 26 May 1898) was a German pianist and music educator.
Born in Dresden, Krantz was the son of the painter Moritz Krantz and Amalia Krantz née Schmidt. He studied at the Hochschule für Musik Carl Maria von Weber in Dresden. In 1865, he took a teaching post in Pomerania, and from 1869 he taught at the Dresden Conservatory.
In the same year, on 17 November 1869, Krantz married the Catholic Marie Antonie Mautsch. Krantz, initially a Protestant, had to convert to the Catholic denomination in order to obtain Marie's father's consent to the marriage.
In 1890, Krantz bought the Dresden conservatory from Heinrich Pudor. From 1896 until his death in 1898 at the age of 53, he simultaneously directed the Dresden Singakademie. His grave is located at the Trinitatisffriedhof.
