Ryan James Jack (born 27 February 1992) is a Scottish professional footballer who plays as a central midfielder for TFF First League club Esenler Erokspor and the Scotland national team.

[4] On 13 December 2011 in a Scottish Premier League fixture against St Johnstone, he scored a goal from the halfway line to put his team 2–0 up after opposing goalkeeper Peter Enckelman miskicked a clearance.

[20] He made his debut against Luxembourgish side Progrès Niederkorn in the first qualifying round of the 2017–18 UEFA Europa League on 29 June 2017, a tie which Rangers lost 2–1 on aggregate after losing 2–0 away from home.

[21] On Rangers' first visit to Aberdeen since his move, Jack started the game but was sent off in the second half for a bad tackle, although his team won the match 2–1.

[23][24][25] In January 2018, Rangers confirmed that Jack required surgery on a knee injury sustained in a match the previous month, ruling him out of action for some time.

[33] Jack signed a one-year contract extension with Rangers in May 2023,[34] but missed much of the subsequent season through injury and was allowed to depart on a free transfer in June 2024.

[37] Jack eventually made his full Scotland debut in a friendly against the Netherlands in November 2017, by which time he had moved from formative club Aberdeen to Rangers.

The match happened to take place in Aberdeen, and in the opening stages he was booed whenever he touched the ball by some of the crowd, due to the rivalry between those clubs and the ill-feeling his transfer had stirred; other fans responded to this by cheering and applauding him.

[30] In contrast, he was selected for the Scotland squad for UEFA Euro 2024 despite taking part in few matches at club level in the months leading up to the tournament;[40] he did not make an appearance in Germany as the team were eliminated at the group stage.
