Irene Scharrer (2 February 1888 – 11 January 1971) was an English classical pianist. Irene Scharrer was born in London and studied at the Royal Academy of Music with Tobias Matthay. She made her London début at the age of 16, and gave concerts regularly until June 1958, where she appeared for the last time, playing Mozart's Sonata for Two Pianos with Myra Hess. They often performed four-handed compositions together. Scharrer is sometimes erroneously described as Hess's cousin. She was distantly related to another fine woman pianist, Harriet Cohen, the two sharing a great-great-grandfather.
