James Charles Mackie (born 22 September 1985) is a former Scotland international footballer who played as a striker or winger, most notably for Queens Park Rangers, Plymouth Argyle, and Oxford United.

Mackie began his career at Wimbledon, progressing through the club's youth system and making his first-team debut in December 2003. A squad member when the club was renamed and moved to Milton Keynes, he made few appearances before joining Conference side Exeter City. He spent time on loan with Sutton United in 2005 and returned to establish himself as a first-team regular. His performances during the 2007–08 season attracted interest from other clubs and he signed for Plymouth Argyle in the January transfer window, scoring twice on his debut in the Championship. He appeared regularly for the club over the next two years and finished as the club's top goalscorer in the 2009–10 season. He joined Queens Park Rangers in May 2010, signing a four-year contract for an undisclosed fee. In 2013, he joined Nottingham Forest before signing on loan for Reading in 2014 and then returning to QPR in 2015. In July 2018, at the age of 32, he signed a two-year contract with Oxford United of League One. He retired from professional football in 2020.

Born in Dorking, Surrey, Mackie attended The Ashcombe School in Dorking.

Mackie began his career at non-league Leatherhead, joining Wimbledon as a trainee in 2003, before moving to Exeter City in August 2005. Following a brief loan spell at Sutton United in his first season, Mackie went on to become an established first-team player, scoring more than 20 goals in all competitions, from nearly 100 appearances, thus alerting other clubs of his potential.^{[citation needed]}

After handing in a transfer request, Mackie signed for Plymouth Argyle, who had fought off competition from Bristol City, Norwich City, Bristol Rovers and Cheltenham Town, for an initial fee of £145,000. In his first appearance for Plymouth Argyle on 12 February 2008, coming on as a substitute against Barnsley, Mackie scored within eleven seconds of his arrival on the pitch, thus breaking the record held by Tony Witter for the fastest goal scored for Plymouth Argyle on a debut. He would go on to score a second in that game. He was featured 13 more times that season, mainly as a substitute, scoring his third goal for the club against Preston North End on 19 April 2008.

Mackie established himself as a first-team player during the 2008–09 season, making 45 appearances in all competitions, with the highlight being a 25-yard strike against Reading at Home Park. Having started life with the Pilgrims primarily as an impact substitute, Mackie subsequently became a regular name in the club's starting line-up. He played 44 times during the 2009–10 season, scoring a total of eight goals, although this was not enough to keep Plymouth in the second tier of English football.

In May 2010, Mackie signed a four–year contract with Queens Park Rangers for an undisclosed fee. Signed by Neil Warnock in what would be a Championship-winning season, he was mainly employed in a right wing or midfield position in Warnock's new 4–2–3–1 formation. Mackie got off to a good start at QPR, scoring on his debut in a 4–0 win over Barnsley. By mid-September Mackie had put himself top of the Championship goalscorers list with eight goals coming in his first seven league games, scoring doubles against Ipswich Town and Leicester City. He failed to score for 13 matches until netting the first in a 4–0 win over Swansea City on Boxing Day 2010. On 8 January, during an FA Cup tie against Blackburn Rovers, Mackie sustained a double tibia and fibula break during a collision with Rovers player Gael Givet. The injury kept the player out for seven months until he returned to training in September 2011. Although on the sidelines for the second half of the season, he had still participated enough to be awarded a Championship winner's medal^{[citation needed]} as the team earned promotion to the Premier League for the first time in 15 years.

Mackie returned to QPR's first team with a substitute appearance in the October 2011 match at Fulham and then started his first Premier League match at home to Blackburn Rovers two weeks later. Mackie scored his first Premier League goal in a 3–2 home defeat to Sunderland. His return to the side saw him feature regularly under Neil Warnock until the manager was replaced in January 2012 by Mark Hughes. Under Hughes, Mackie continued to occupy a wide-midfield berth and featured in the victory against Wigan Athletic and the subsequent draw with Aston Villa. Replaced by Adel Taarabt (who returned from the 2012 Africa Cup of Nations) for the game against Wolves which ended in defeat, he came off the bench in the 66th minute to replace Akos Buzsaky against Blackburn Rovers at Ewood Park with the score 3–0 to the home side. He scored twice to bring the score back to 3–2 and nearly grabbed an equaliser to push for a regular place in the side. Mackie came off the bench for Joey Barton in the home game against Liverpool to inspire a comeback from 2–0 down, scoring the winner in a 3–2 victory at Loftus Road. He also scored QPR's second goal in the final match of the 2011–12 Premier League season in a 2–3 loss to Manchester City, who were crowned Champions that day.
