Peter Paul Fuchs (October 30, 1916 – March 26, 2007) was an Austrian-born conductor and composer, best known for his conducting appointments with American orchestras and for his teaching.

After his academic studies in the "gymnasium", he graduated in 1935 from the Vienna Academy of Music where his mentors were Felix Weingartner and Joseph Krips in conducting, and Karl Weigl in composition.

Fuchs arranged for his parents to leave Nazi occupied Austria in 1940, and brought them to America; two years later he was inducted into the army and automatically became an American citizen.

Following the end of hostilities in 1945, he returned to the Metropolitan Opera as a full-time staff conductor until 1950 working with Bruno Walter, George Szell, Fritz Reiner, Erich Leinsdorf, Ettore Panizza, and others.

His writing included two notable books, The Musical Theater of Walter Felsenstein (W. W. Norton) and The Psychology of Conducting (MCA), which has become required reading in many universities.

He directed many opera workshops notably at the Manhattan School of Music where, in 1962, he conducted the premier of Jan Meyerowitz's "Godfather Death".
