William Bannon (c. 1826 – 27 February 1904) was an Irishman who served in the British 65th Regiment of Foot in the New Zealand Wars in the 1840s. In 1849 he was found guilty of desertion and theft and was sentenced to transportation for seven years to Van Diemen's Land (now Tasmania, Australia). A reward was posted for Bannon's capture after he escaped from a prison in Van Diemen's Land and, following his capture, he was transported to Norfolk Island before returning to Australia. "Murdering Gully Rd" at Table Cape, Tasmania is named after a murder that Bannon was accused of committing in 1858.
