Sir Samuel Gillott (29 October 1838 – 29 June 1913) was an Australian lawyer and politician, commonly known as a former Lord Mayor of Melbourne.

During the 1890s, Gillott specialized in police court practice, with a firm exception being the Speight v. Syme libel case.

Promoted to Lord Mayor in 1901, Gillott was knighted in the same year during the visit to Australia of the Duke and Duchess of Cornwall and York (later King George V and Queen Mary).

As proof, Judkins named John Wren's illegal betting schemes, which he held as evidence of a corrupt government.

Following the gambling controversy, John Norton's newspaper, The Truth, published an article on Gillott, linking him to a well known brothel proprietor, Caroline Hodgson, and revealing his financial dealings with her since 1877.
