Geoffrey Penwill Parsons AO OBE (15 June 1929 – 26 January 1995) was an Australian pianist, most particularly notable as an accompanist to singers and instrumentalists.

After the retirement of Gerald Moore, he was generally considered the world's finest and most sympathetic accompanist of lieder singers, "elevating the role of the accompanist to new heights with his musicality, authority and quiet strength of playing".

David Garratt wrote:

Claims of superiority are debatable in the arts, where precise measurement is impossible and subjectivity is the norm. Australians often ask themselves whether we've matched the world standard, but one claim will rarely be debated by knowledgeable music lovers: that the Australian Geoffrey Parsons had no peer as a singer's accompanist.
