Eleanor Everest Freer (14 May 1864 – 13 Dec 1942) was an American composer and philanthropist.

She taught music in Philadelphia and New York City, and married Chicago doctor Archibald Freer in 1893.

The couple had one daughter and moved to Chicago in 1899, where Eleanor Freer studied music theory with Bernard Ziehn.

To this end, she helped to found the Opera in Our Language Foundation (OOLF) in 1921, and the David Bispham Memorial Fund in 1922 to promote concerts of American composers' works and award a Bispham Medal.

[6] Freer composed eleven operas and more than 150 songs, many of which were published in collections.
