Archibald G. Logan (died 11 July 1949) was a Scottish trade unionist and politician. Logan worked as an iron moulder in Falkirk. In 1888, he took part in a strike for increased wages. Following the action, the strikers formed the Central Ironmoulders' Association, and Logan was elected to its first committee. The union grew quickly, and in 1904 he led a delegation to investigate working conditions in the light castings trade in England. Workers in England began joining the union, and in 1906 Logan was posted to England to organise those branches.
