John Jack (9 March 1932 – 22 October 1988) was a Scottish footballer who played for Celtic and Morton.{{NeilBrownPlayers|player4/johnjack}}

At Celtic, where he spent nine years, he was mainly a reserve behind Jim Mallan, Alec Boden and Jock Stein, with Bobby Evans also being asked to fill in rather than calling upon the inexperienced Jack even in minor competitions. However he did feature regularly in the 1956–57 season,[https://www.fitbastats.com/celtic/player.php?playerid=2599 (Celtic player) Jack, John)], FitbaStats during which he won the Scottish League Cup with the Hoops overcoming Partick Thistle in the final after a replay to win that competition for the first time.{{cite web|url=http://www.thecelticwiki.com/page/1956-10-31%3A+Celtic+3-0+Partick+Thistle%2C+League+Cup+Final+Replay|title=Celtic win League Cup for first time |work=The Herald|location=Glasgow|date=1 November 1956|via=The Celtic Wiki|access-date=30 October 2018}} When Stein retired and took over the reserve team, Jack assisted until he departed in 1959, spending a short period with Morton.

Born Jonas Kaduskevieche, he was one of four Scots of Lithuanian descent to play for the club between the 1930s and 1960s, all of them defenders,[https://thecelticstar.com/matt-corr-and-they-gave-us-james-mcgrory-and-danny-dawson/6/ And they gave us James McGrory and Danny Dawson], Matt Corr, The Celtic Star, 18 March 2020[https://www.celticquicknews.co.uk/ever-footballer-has-a-story-especially-if-he-played-for-celtic/?cmpredirect Every footballer has a story, especially if he played for Celtic], Michael Beattie, Celtic Quick News, 11 March 2017 the most famous being Billy McNeill who joined as a teenager in 1957 and quickly overtook Jack in the queue for team selection.
