William Dorrinton (29 April 1809 – 8 November 1848) was an English first-class cricketer who played for Kent, Hampshire, Suffolk and the Marylebone Cricket Club in a 94–match career which began in 1836 and lasted until 1847, a year before his death. While Dorrinton has two first–class wickets to his name, he became a wicket keeper part–way through his career, taking 89 catches and performing 25 stumpings.
