John Nicol Robertson (1884 – 23 January 1937) was a Scottish professional footballer who played at half-back for various clubs in the early 20th century, spending most of his career with Southampton.
Robertson was born in Ochiltree in South Ayrshire and after spending time with Rangers in Glasgow, moved to England in April 1902 to join Bolton Wanderers of the Football League Second Division.
Described in the local press as "a really classy half-back and an exceedingly capable player",[1] Robertson made his debut for the "Saints" on 8 September 1906, playing at left-half in a 2–2 draw with Norwich City.
[1] This season saw his longest period of regular first-team football, when he missed only one match[7] before he was sold to Rangers in March 1912, much to the dismay of the Saints' supporters.
Robertson spent only one full season at Ibrox in which he made sixteen appearances at left-back, 12 in the Scottish Football League which concluded with Rangers as champions, plus four in the Glasgow Cup when the Gers defeated local rivals Celtic 3–1 in the final.
