Robert Scott Lauder RSA (Edinburgh 25 June 1803 – 21 April 1869 Edinburgh) was a Scottish mid-Victorian artist who described himself as a "historical painter". He was one of the original members of the Royal Scottish Academy.
Lauder was born at Silvermills, Edinburgh, the third son of John Lauder of Silvermills (d. 1838), Burgess of Edinburgh and proprietor of the tannery at Silvermills, by his wife Helen Tait (d.1850). After attending the Royal High School he went to London, where his eldest brother William was engaged in the family business.
He returned to Edinburgh about 1826 and was elected one of the original members of the Royal Scottish Academy in 1830. At this point Lauder was living with his brother William Lauder at 24 Fettes Row in the northern fringe of Edinburgh's Second New Town. On 9 September 1833 at St.Cuthberts in Edinburgh he married Isabella Ramsay Thomson and they then went abroad, accompanied by his younger artist-brother, James Eckford Lauder. Robert studied for some years in Rome, Florence, Bologna, Venice and Munich.
Lauder returned to London in 1838 where he lived for several years, where his three children — Isabella, John, and Robert — were baptised at St.Thomas’s Church, Southwark, in 1840, 1841, and 1844 respectively. Whilst in London he exhibited at the Royal Academy and competed in the Westminster Hall competition of 1847, sending his Christ walking on the Sea, which was subsequently purchased by Lady Angela Burdett-Coutts, 1st Baroness Burdett-Coutts. He became the first president of the short-lived National Institution of Fine Arts and also exhibited there.
