Rupert Theodore "Rufus" Naylor (14 August 1882 – 25 September 1939) was an Australian sporting entrepreneur and gambler.
He travelled to South Africa in 1908 with a number of athletes and in 1909 organised a Johannesburg event between Jack Donaldson, Arthur Postle and Charles Holway; his business expanded to include a stadium and a cinema chain.
He continued his sporting and gambling interests until 1930, when he ran a scam to sell "shares" in lottery tickets.
He ran unsuccessfully as an independent candidate for the seat of Lang in the 1934 federal election and was banned from registered racecourses later that year having allegedly given false information to the Australian Jockey Club's committee.
He successfully challenged the ruling in the Supreme Court but the Jockey Club appealed to the Privy Council to have their ban upheld.
