Peter Thomas Marner (31 March 1936 – 16 May 2007) was an English cricketer who played first-class cricket for Lancashire and then Leicestershire. He was rated by Trevor Bailey as the most formidable English batsman without a Test cricket cap. Marner is also in the record books for being the first person to win a limited-overs Man of the Match award, when Lancashire played its first Gillette Cup match against Leicestershire at Old Trafford in May 1963. He scored the format's maiden century in that game with an innings of 121, and also took 3 wickets for 49 runs.
