Michael Raucheisen (born: 9 February 1889, Rain, Swabia, Germany - died 27 May 1984, Beatenberg, Switzerland) was a German pianist and song accompanist. He married Hungarian soprano Maria Ivogün in 1933.

He was most active before the end of the Second World War, coming out of retirement for a 1958 tour with Elisabeth Schwarzkopf, before once more returning to private life in Switzerland.

The bulk of his recordings are from the pre-stereo era. The conducting credits are highly suspect (especially those from after 1984!), and are often given on releases involving known fictitious conductors like Henry Adolph: please use Michael Raucheisen in such instances.
