Elizabeth Quaile (January 20, 1874 – June 30, 1951) was an American piano pedagogue of Irish birth.
A native of Omagh, Quaile emigrated to the United States early in her life; she settled in New York City, and undertook studies with Franklin Robinson before turning to teaching.
From 1916 until 1919 she chaired the piano department of the David Mannes School; she then traveled to Paris for more study, taking lessons with Harold Bauer.
In 1921 she returned to New York, founding the Diller-Quaile School of Music with Angela Diller that same year.
Quaile, sometimes together with Diller, produced a number of books and other works to be used in the teaching of piano, many of which saw much success.
