John Neil Henderson was a Scottish professional football player who played in the Scottish Football League for Celtic and in the Football League in England for Lincoln City, Leicester Fosse and Small Heath.
Henderson was born in Dumfries.
He began his football career with the 5th Kirkcudbright Rifle Volunteers before joining Celtic in 1895, where he made his debut in the Scottish Football League on 12 December 1896 as Celtic beat Clyde 4–1. After scoring 10 goals in 82 appearances in all competitions (9 in 76 in the league), Henderson joined Leicester Fosse in December 1900, but stayed only three months before moving on to Small Heath. The club had hoped his arrival would strengthen their push for promotion, but he played only four times before returning home.
Henderson played out his career in Scottish football, apart from a short spell with Carlisle United in the Lancashire Combination, continuing until at least his late thirties.
Henderson died in Maxwelltown, Dumfries, in 1930 aged about 59.
