Joseph Thomas Gordon Shaughnessy (born 6 July 1992) is an Irish professional footballer who plays as a centre-back for and captains Scottish Premiership club Dundee.

[4] Shaughnessy signed for Aberdeen in June 2009, having previously played for Irish club Salthill Devon as a youngster.

Ahead of the 2012–13 season, manager Craig Brown believed Shaughnessy and Low had performed well at Forfar Athletic and considered him using them in the first team in the near future.

[18] He scored his first competitive goal for Aberdeen four days later in the Scottish Cup 4th Round Replay win over Motherwell.

[23] Shaughnessy subsequently had his first team opportunities limited, as Shaleum Logan or Ryan Jack were preferred in the right-back position.

[27] Following his return, Shaughnessy made two more appearances, including making his first start, in a 1–0 loss against St Johnstone in the last game of the season.

[37] He would make his competitive debut in an away Scottish League Cup group stage win against Bonnyrigg Rose.

[38] Shaughnessy scored his first two goals for the club in quick succession on 28 October as he netted a late brace to clinch a win away to Livingston.

[41] Having played in every minute of Dundee's impressive season in which they had achieved top six, Shaughnessy would suffer a "significant" knee injury early into a league draw at home to Rangers in mid-April 2024, which was confirmed a few days later to have ended his season following confirmation that the injury was a ruptured ACL.

[46][47] Three days later, Shaughnessy made his first competitive appearance for Dundee since April 2024 as a substitute in a Scottish Cup fifth round victory over Airdrieonians.
