Erna Tauro (16 August 1916 – 4 June 1993) was a Finnish pianist and composer. She was a close friend and constant collaborator with Tove Jansson, from 1958 to her death she was involved with composing Moomin related music. Mostly she would compose around Jansson's lyrics, but in some cases she also made purely instrumental background music.
Apart from the Moomin related songs, the two would also collaborate on unrelated compositions. Among them Höstvisa (Autumn Song) from 1965, which became rather popular with Swedish speaking audiences and covered by other artists several times. The 1977 Cumulus cover reached no. 1 on the Swedish song charts.
