Sir Robert Kyffin Thomas (19 August 1851 – 13 June 1910)[1] was a South Australian newspaper proprietor.
He also printed the first Government Gazette, but lost that business when he ran foul of Governor Gawler.
He was admitted as a partner in the firm in 1877, and at the time of his death he was the senior proprietor of The Register.
While in Great Britain in 1902 Thomas helped form the committee which commissioned Captain Adrian Jones to create the South African War Memorial, to be seen on the corner of King William Road and North Terrace, Adelaide, in front of Government House.
On the same trip he acquired a number of paintings for the National Gallery of South Australia.
