Marjorie Olive Hayward (14 August 1885 – 10 January 1953) was an English violinist and violin teacher, prominent during the first few decades of the 20th century.

An "infant prodigy",[1] her violin studies were with Émile Sauret at the Royal Academy of Music in London (1897–1903), and Otakar Ševčík in Prague (1903–06).

[2] Her two years in Prague were paid for by the sale of the family home: Hayward later expressed her gratitude for this and other support from her musical mother.

She led the English String Quartet (which included Frank Bridge on viola), and later the Virtuoso Quartet, the first chamber music group formed specifically for making recordings, with Edwin Virgo (2nd violin), Raymond Jeremy (viola) and its founder Cedric Sharpe (cello).

The Quartet did not confine itself to recordings but also broadcast and toured frequently, its repertoire extending to quintets with artists such as Harriet Cohen, William Murdoch, Arnold Bax and Léon Goossens.
