Jack MacKenzie, born 4 July 2000 (age 26), is a Scottish left-back now with Plymouth Argyle, where he wears number 3. At 6ft 3in (1.91m), he is an imposing full-back rather than the usual low-slung type in that role.
His career is shaped far more by Aberdeen than by anywhere else. Early loan football helped move him from prospect to senior player, but Aberdeen is where the substance of his record sits: 96 league appearances and two league goals across five seasons. His most productive league campaign came in 2021-22, when he scored once in 20 appearances.
MacKenzie has since moved on to Plymouth Argyle. In 2026-27, he has made three appearances across League One and the EFL Trophy. His current market value is around £680,000, according to Transfermarkt.
It is a career still led by his Aberdeen spell: a long, steady run there, followed by the attempt to establish himself in England with Plymouth.
