Mark Reynolds (born 7 May 1987) is a Scottish professional footballer who plays as a defender for Highland League club Banks o' Dee.

[8] Reynolds would stay at Motherwell for another season[9] and stated he would prefer to play in the English Premier League than join either of a Scotland's Old Firm clubs.

In the 2009–10 season, Reynolds played in all six games of Motherwell's Europa League campaign where the club were eventually eliminated by Steaua București.

[11] On 31 August 2010, it was reported that Swansea City had put in a bid for the defender, which was turned down by Motherwell as it did not meet their valuation for the player, who was in the final year of his contract.

After being told by Sheffield Wednesday manager Dave Jones that he was surplus to requirements and won't get first team guarantee,[21] Reynolds returned to Aberdeen on loan for the 2012–13 season.

[22] Upon arriving for the second time, Reynolds said he joined Aberdeen instead of Rangers as "it's a strange situation there at the moment", as the Glasgow team had been re-admitted to the bottom tier of the Scottish leagues.

[24] The following month, Aberdeen chief executive Duncan Fraser announced that the club had opened negotiations to sign Reynolds on a permanent deal, with a possible three-year contract on the table.

[29] At that time, former Aberdeen captain Willie Miller compared Reynolds's central defensive partnership with Russell Anderson to his own successful pairing with Alex McLeish.

[30] The following month, Reynolds started in the 2014 Scottish League Cup Final victory against Inverness Caledonian Thistle, his first domestic honour and Aberdeen's first piece of silverware in 19 years.

[31] In the 2014–15 season, Reynolds featured in six matches in the Europa League and scored his first European goal in the second leg of third round, as Aberdeen lost 3–2 to Real Sociedad.

[35] During his loan spell, he signed a pre-contract agreement with United;[36] his arrival on a three-year contract was confirmed in June 2019, despite the club failing to win promotion.

"[5] He was held up as an example to aspiring local footballers (such as future Aberdeen teammate Mikey Devlin who lived on the same street) for achieving academically as well as in sport.
