"Allerseelen" ("All Souls' Day") is an art song for voice and piano composed by Richard Strauss in 1885, setting a poem by the Austrian poet Hermann von Gilm from his collection Letzte Blätter (Last Pages). It is the last in a collection of eight songs which were all settings of Gilm poems from the same volume entitled Acht Lieder aus Letzte Blätter (Eight Songs from Last Pages), the first collection of songs Strauss ever published as Op. 10 in 1885, including also "Zueignung" (Dedication) and "Die Nacht" (The Night). The song was orchestrated in 1932 by German conductor Robert Heger.
