Robert George Deans (19 February 1884 – 30 September 1908) was a New Zealand and Canterbury rugby union footballer.
In 1905, Deans entered New Zealand rugby folklore for his disallowed try against Wales in the famous Match of the Century.
Deans claimed to have scored a try that would have drawn New Zealand level but was pulled back over the line before the referee could catch up.
Deans was 24 years old when he died as a result of complications arising from an appendix operation.
