Wyndham William Knight (5 December 1828 – 17 September 1918), known in some sources as Wiliam Wyndham Knight, was an English amateur cricketer who played in one first-class cricket match for Kent County Cricket Club in 1862. Knight was born at Chawton in Hampshire in 1828 and educated at Winchester College. He is known to have played cricket twice for the amateur Gentlemen of Kent side in the 1850s before making his only first-class appearance for the county side in 1862 against Sussex. He was one of the founders of the Band of Brothers, an amateur cricket club closely associated with Kent.
