Malcolm MacDonald (26 October 1913 – 26 September 1999) was a Scottish professional footballer and manager, best remembered for his time as a utility player with Celtic and as a manager with Kilmarnock and Brentford. MacDonald managed the Scotland national team on a caretaker basis in 1966. He is a member of the Brentford Hall of Fame.

MacDonald began his career in Glasgow with junior clubs St Roch's and St Anthony's, before signing for Scottish First Division club Celtic on 19 March 1932. Playing as an outside left, he had a dream debut, scoring both of Celtic's goals in a 2–0 victory over Partick Thistle in the final league match of the 1931–32 season. Though he built on his appearance record year-by-year to make 38 appearances during the 1934–35 season, the arrival of Willie Lyon and a cartilage problem saw MacDonald's chances limited in 1935–36, making just 11 appearances during a season in which Celtic won the First Division title for the first time in 10 years.

MacDonald didn't fully break into the team on a regular basis until the departure of Willie Buchan to Blackpool in November 1937. He made 34 appearances and scored 13 goals during the 1937–38 season, helping the Bhoys to the league title and the Empire Exhibition Trophy. MacDonald's best season came in 1938–39, scoring 20 goals in 40 games and scoring a hat-trick in the Old Firm match on 10 September 1938. The outbreak of the Second World War in September 1939 saw competitive football suspended for the duration of the conflict, but MacDonald remained with Celtic, making 199 wartime appearances (18 goals) before the official leagues and cups resumed in 1946. MacDonald departed Celtic after the war, having made 156 appearances in major competitions and scored 38 goals during his time with the club. He played in every position bar goalkeeper during his years at Celtic Park.

MacDonald returned to Southern League 'A' club Kilmarnock in 1945, after a period guesting in 1940 during the Second World War. He remained at Rugby Park until October 1946. MacDonald would later play for the club again while manager during the 1951–52 season. He made 10 appearances and scored one goal across his two spells with the club.

MacDonald moved to England to join First Division club Brentford for a £1,500 fee in October 1946. Manager Harry Curtis played him as an inside forward, but a broken jaw hampered his progress and the Bees were relegated to the Second Division at the end of the 1946–47 season. Injury to Bill Gorman saw MacDonald take up a position at full back in September 1947 and he kept the position until his retirement at the end of the 1948–49 season. He made 93 appearances and scored one goal during his time at Griffin Park.

MacDonald's first taste of international football came with the Scotland schoolboy team in 1928. In 1939, he made 8 appearances for the Scottish FA XI on its tour of Canada and the United States. He later won three wartime caps for the full Scotland team during 1941. MacDonald represented the Scottish Football League XI against their English counterparts on 11 October 1941.

MacDonald briefly coached the Scotland national football team for wartime internationals played in 1945.

MacDonald's coaching career began while still a player at Brentford and he held a player-coach role during the 1948–49 season.
