The Grainger Museum is a repository of items documenting the life, career and music of the composer, folklorist, educator and pianist Percy Grainger (b. Melbourne, 1882; d. White Plains, New York, 1961), located in the grounds of the University of Melbourne, Victoria, Australia.

[4] Designed specifically to fulfill the role envisioned by Grainger, it is the only purpose-built autobiographical museum in Australia.

[6] The Grainger Museum was closed in 2003 for seven years, for restoration and conservation work, after waterproofing issues were detected.

Among displays of original manuscripts and published scores, musical instruments, field recordings, artworks, photographs, books and personal items, are Grainger’s whips and other items relating to his sado-masochism (which Grainger called the "Lust Branch"), the contents of his bedside cabinet, and a gallery devoted to his mother’s suicide.

The substantial archival collection includes some 50,000 items of correspondence (Grainger corresponded with people such as Edvard Grieg, Frederick Delius, Cyril Scott, Roger Quilter and Julius Röntgen, and collected letters of Wagner and Tchaikovsky among others).
