Samuel Richard Lewes Elliott (21 April 1860 – 14 July 1933) was an Australian pastoralist and politician who served as a member of the Legislative Assembly of Western Australia from 1913 to 1914 and for a brief period in 1917, on both occasions representing the seat of Geraldton.
He arrived in Western Australia in 1875, at the age of 15, and began working on Theodore Fawcett's estate at Pinjarra.
In 1880, Elliott was involved in the formation of the Murray Squatting Company, along with two other future MPs, Alexander Richardson and William Paterson.
However, Heitmann resigned from parliament in March 1917 in order to stand for the House of Representatives, and Elliott reclaimed Geraldton at the resulting by-election.
His second term in parliament lasted only five months, as he was beaten by John Willcock (a future Labor premier) at the 1917 state election, where the final margin was just 31 votes on the two-candidate-preferred count.
