An Sylvia, D. 891; Op. 106, No. 4, is a Lied composed by Romantic era composer Franz Schubert in 1826 and published in 1828. The text of the lied is a German translation of the poem, "Who is Sylvia", from Act 4, Scene 2 of the play, The Two Gentlemen of Verona, by William Shakespeare. The text was translated into German from English by Eduard von Bauernfeld, and the song is scored for voice and piano. An Sylvia was composed during a peak point in Schubert's career around the time he was writing the Ninth Symphony "Great" (D 944) just two years before his death.
