Robert Bliss Wilkinson (1838 – 26 April 1928) was an English-born Australian politician.
He was born in Northampton to engineer David Wilkinson and Elizabeth Bliss.
From 1853 he worked for the Castlemaine and Maryborough branches of the Bank of Victoria.
On 15 November 1882 he married Alice Georgiana Foss Jarrett; they had no children, but a second marriage on 26 February 1890 to Annie Louise Leitch (née Lavender) resulted in three children.
Robert Bliss and Annie Louisa Wilkinson are buried directly alongside Alice Georgiana Foss Wilkinson behind St. Thomas' church in South Strathfield (formerly known as Enfield).
