Edith Best (11 July 1865 – 9 March 1950) was an Irish musician and one of the founding members of the Feis Ceoil.

She attended the Royal Irish Academy of Music (RIAM), studying under Margaret O'Hea and Robert Prescott Stewart.

She was a close friend and confidante of the College's director, Sir George Grove, to which his 514 letters to her from 1883 to 1899, now housed in the RCM library, testify.

Best was a founding member of the Feis Ceoil, undertaking large responsibility for its organisation, and it became an annual event under her leadership.

In 1898, she described the foundation of the Feis in a paper to the Incorporated Society of Musicians as being inspired to "ultimately do more for the art of music in Ireland than anything which has yet been attempted.
