John 'Jock' Stein CBE (5 October 1922 – 10 September 1985) was a Scottish association football player and manager. He became the first manager of a British side to win the European Cup, with Celtic in 1967. Stein also guided Celtic to nine successive Scottish League championships between 1966 and 1974.

During his managerial career he won the European Cup once, ten Scottish League Championships, nine Scottish Cups, and six Scottish League Cups. All but one of these honours (the 1961 Scottish Cup with Dunfermline) were won with Celtic. After a brief stint with Leeds United, Stein managed the Scottish national side from 1978 until his death in 1985. Stein was voted the greatest Scottish football manager in a 2003 poll by the Sunday Herald newspaper.
