Jack MacKenzie, born on 4 July 2000 (age 26), is a Scottish left back now with Plymouth Argyle, where he wears the number 3 shirt. A tall full-back at 6ft 3in (1.91m), he has a current market value of around £680,000, according to Transfermarkt.
His career has been shaped above all by Aberdeen. Early loan football formed part of his development, but it was at Pittodrie that he became properly established, making 96 league appearances and scoring two league goals across five seasons.
The 2021–22 season was his most productive in league terms, with one goal in 20 appearances for Aberdeen. That was the period when he moved beyond promise and into the regular demands of senior football, without needing to be dressed up as something grander than it was.
MacKenzie later moved to Plymouth Argyle. In 2026–27, he has made four appearances across all competitions, including three in League One and one in the EFL Trophy.
His career to date is straightforward enough: developed through loan football, established over a long spell at Aberdeen, and now continuing in England with Plymouth.
