Norah Simpson (5 July 1895 – 19 February 1974) was an Australian modernist painter.
She grew up in Sydney and is described as "giving impetus to modernism" in Australia: when returning from France in 1913, she brought back a series of reproductions of then-current works which were influential to her fellow art students.
Sydney-based modernists inspired by those works and Simpson's descriptions of techniques include Grace Cossington Smith, Roy de Maistre and Roland Wakelin.
