1st Scots Guards F.C. were an English football team that existed from at least 1891. They played in the Southern League from 1895-96 and finished third of nine in Division Two. This made them eligible to play in a test match promotion decider against Clapton, which they lost 1-4. The following season they finished 8th of 13.
They also participated briefly in the London League Division One for the 1896-97 season before withdrawing, and were the last club to play Thames Ironworks at their Hermit Road ground on 8 October 1896, when they lost 1-0.
They were still a functioning football team as late as 1906.
It is to be noted that the Christmas truce football game of 1914 supposedly featured men from the 1st Scots Guards.
