George Robert Sykes (1867 – July 1957) was a New Zealand Member of Parliament for the Masterton electorate in the North Island.
George Sykes represented the Masterton electorate in the New Zealand House of Representatives for 24 years from 1911 to 1935.
Sykes was a member of the Reform Party, but in 1919 successfully stood as an Independent for Masterton, whilst some commentators questioned whether the independent Reform candidates in 1919 were not just trying to attract votes from the 'unwary'. In 1935, he was awarded the King George V Silver Jubilee Medal. He was awarded a Coronation Medal in 1937.
Sykes was a farmer and sheep breeder.
Sykes was buried in the Historic Church Taita; with a memorial in Archer Street Cemetery in Masterton on 31 July 1957.
