William John Tobin (28 July 1953 – 7 July 2022) was a British–New Zealand astronomer and academic. In the 2019 United Kingdom general election he stood as an independent candidate against Boris Johnson in the Uxbridge and South Ruislip constituency. As he had not resided in Britain for more than 15 years he was ineligible to vote but eligible to stand as a candidate. He focused his campaign on voting rights using the slogan "Don't vote for Tobin, let Tobin vote". He gained five votes.
