Jim Iley (born 15 December 1935 in South Kirkby, Yorkshire) is an English former football player and manager. He made nearly 550 appearances in the Football League playing as a left half for Sheffield United, Tottenham Hotspur, Nottingham Forest, Newcastle United and Peterborough United. As manager, he took charge of Peterborough (as player-manager), Barnsley, Blackburn Rovers, Bury and Exeter City. He was capped once for England under-23 team.
Iley helped Newcastle to seventh and eighth-place finishes in successive seasons, before being part of the 1964/65 Division Two title-winning team, appearing in all but four games and scoring five times.
Later spells in charge of Barnsley, Blackburn Rovers, Bury and Exeter City followed - including some giant-killing over his former club Newcastle when Fourth Division Bury beat the Toon over two legs in the 1980/81 League Cup.
