Sara Wennerberg-Reuter (11 February 1875 – 29 March 1959) was a Swedish organist and composer.
Sara Wennerberg-Reuter received her early musical training in organ and harmony in Gothenburg and studied at the Stockholm Conservatory (1893-1895), graduating as an organist.
Sara Wennerberg-Reuter’s compositions, and especially her male voice quartets, were performed frequently in their day.
Her Easter Hymn, motets and anthems for mixed choir were also part of the standard repertoire, as were her Violin Sonata (1904) and some of her piano pieces.
She also wrote several other cantatas as well as two tone poems for solo voices, choir and orchestra, one called Necken (to a poem by her uncle Gunnar Wennerberg) and the other titled Skogsrået (to a text by Viktor Rydberg) in 1915, were well received.
