Dr. John Smith (born 12 August 1855 in Mauchline, Ayrshire- died 15 December 1937) was a Scottish footballer of the 1870s and 1880s.
Smith began playing football at Mauchline F.C. before transferring to Edinburgh University while he studied. After completing his studies in the early 1880s he joined Queen's Park by which time he had already made several appearances for the Scottish national team.
At Queen's Park he won the Scottish Cup in 1881, 1882 and 1884. He became the first player to score a hat-trick in a Scottish Cup final when he scored all three of Queen's Park's goals in the 1881 final replay against Dumbarton
. He was not selected to play in the 1882 cup final and no final took place in 1884 but Queen's Park were awarded the trophy after Vale of Leven failed to appear for the final.
Smith often played under the pseudonym J.C. Miller. He also played occasionally as a guest for the Corinthians, Swifts and Liverpool Ramblers FC. He was banned from playing for or against any Scottish club or the Scottish national team in 1885 after he played for Corinthians against a professional English club, thus breaching the Scottish Football Association's amateur regulations.
He earned ten caps in total for Scotland, scoring 10 goals.
As well as football, Smith also played rugby. He played for Edinburgh University and Edinburgh Wanderers and in 1876 was a reserve for the Scottish national rugby team.
As a physician, he practised in Brycehall, Kirkcaldy and sometimes officiated as a football referee.
