Constance Jessie Warren (12 August 1905 – 16 October 1984) was an English composer and piano teacher.
Constance studied piano with the Russian pianist Maria Levinskaya in London, and also with Clifford Curzon (who was two year her junior).
She attended the Royal Academy of Music under York Bowen and Benjamin Dale.
Her pupils there included the composer Brian Ferneyhough and the Birmingham Contemporary Music Group principal pianist Malcolm Wilson.
Duncan Honeybourne has recorded her Idyll in G-Flat Major (1930) in which, he says, "an intense chromaticism lends an emotional depth and ambiguity to the thematic material".
