was a Scottish professional footballer. Born in Motherwell, he played for Parkhead at junior level as an amateur and was one of the most sought-after young players in Scotland before signing for his hometown club, Motherwell F.C., to begin his professional career. He established himself as a consistent scorer playing as a centre forward, finishing as the top goalscorer in the Scottish Football League on three occasions between 1918 and 1921. His 284 league goals remains a record at the club and, by 1925, he was the highest-scoring player in the history of the Scottish League.

In 1925, Ferguson moved to Welsh side Cardiff City for £5,000 (equivalent to £360,000 in 2023) and continued his scoring exploits. He was the club's top goalscorer for four consecutive seasons and scored the winning goal in the 1927 FA Cup Final during a 1–0 victory over Arsenal. He also scored in the 1927 FA Charity Shield, during a 2–1 victory over amateur side Corinthians. Both results made Cardiff the only non-English team to have won the FA Cup or the FA Charity Shield. Despite his prolific scoring record, finishing his career with a goal average of 0.855 per game, he was never selected to play for Scotland, but did represent a Scottish League XI on three occasions.

Ferguson returned to Scotland with Dundee in 1929, but struggled to reproduce his goalscoring form. Six months after his arrival, he had lost his place on the team. He committed suicide on 8 January 1930 at the age of 34. He is one out of only seven men in the history of the English and Scottish Football Leagues to have scored 350 league goals.
