John Adshead ONZM (born 27 March 1942) is an English-born former head coach of New Zealand's national football team—the All Whites—whom he led to their first FIFA World Cup appearance in the 1982 tournament.

[1] With his club Manurewa he won six trophies including the Chatham Cup in 1978 and promotion into the top division in New Zealand the same year.

He successfully led the team to the 1982 FIFA World Cup after they overcame the Rudi Gutendorf led Australia as well as Indonesia, Fiji and Chinese Taipei in the first qualifying round before meeting Kuwait, Saudi Arabia and China in the second round, eventually finishing joint second with China, against whom New Zealand won a playoff 2–1 in Singapore to qualify for the World Cup for the first time in their history.

A cancer scare just after his appointment and the poor on-field performances of the club led to his retirement after the end of the 2005–06 season.

In the 2013 Queen's Birthday Honours, Adshead was appointed an Officer of the New Zealand Order of Merit, for services to football.
