Gary "Gus" John Gilmour (26 June 1951 – 10 June 2014) was an Australian cricketer who played in 15 Tests and five One Day Internationals (ODIs) between 1973 and 1977.
At the peak of his career, Gilmour combined "talented hitting" with "penetrative" left-arm swing bowling and strong slip catching.
He earned comparisons to the Australian all-rounder Alan Davidson.
He was called "Newcastle's greatest all-rounder and arguably its greatest cricketer".
