The Flute Sonata in G major, Op. 87 , is a composition for piano and flute by Ferdinand Ries that was published at The Regents Harmonic Institution in London in 1819. Little information about the works composition history is known as the composers manuscript is undated, but Alan Bradly in the preface to the score published by Artaria Editions indicates that the work may have been composed around 1815 along with a number of other works for the same instrumental combination.
