John Gilligan (footballer, born 1884)
John Ross Gilligan was a Scottish footballer who played as a defender, almost solely for Clyde.
In his first season with the club, he won the 1904–05 Scottish Division Two title. The team was relegated, but gained promotion again in 1906 and retained their place in the top tier for the rest of his time there, including two third-place finishes which equal their all-time highest placings. He also played in the 1912 Scottish Cup Final which Clyde lost to Celtic.
The sole representative honour Gilligan received was a selection for the Glasgow Football Association's annual challenge match against Sheffield in 1909. In 1911 he was granted a benefit match against his hometown club Dundee.
He was the youngest of four brothers who were professional footballers, the others being Sandy, Billy and Sam.
