James John "Jock" Fleming (September 1864 – August 1934) was a Scottish footballer who played at centre-forward for Southampton St. Mary's, Aston Villa and Lincoln City in the 1890s.
Fleming was born in Leith, near Edinburgh and played for Vale of Leven in the early years of the Scottish Football League before joining the army with the 93rd Argyll and Sutherland Highlanders.
The St. Mary's management were so impressed by Fleming and his team-mate, Sandy McMillan, that they immediately signed them both in order that they might play in the forthcoming FA Cup match with Reading.
[2] With this he immediately sent a telegram of protest accompanied by the necessary fee of 2 guineas[3] to the Football Association claiming that the Saints had fielded illegally registered players in Fleming and McMillan.
He scored twice on his debut in a 4–1 victory over Everton,[5] but only made three further (goal-less) appearances for Villa, before moving to join Lincoln City in October 1892.
