The Flute Sonata in E minor, HWV 359b, was composed around 1724 by George Frideric Handel for flute and keyboard (harpsichord). The work is also referred to by its Opus number (1 no. 1b), and was first published in 1732 by Walsh. Other catalogues of Handel's music have referred to the work as HG xxvii,6; and HHA iv/3,10.
