Alfred Barton (30 July 1868 – 9 December 1933) was a British socialist politician. Born in Kempston in Bedfordshire, Barton began working in a library at the age of twelve. He joined the Socialist League at some point in the 1880s, then in about 1890, he moved to Manchester, where he quickly found work at the John Rylands Library. At this time, Alf was on the anarchist wing of the Socialist League, and was prominent in the protests following the police provocations against Walsall Anarchists. Although he was arrested several times for making speeches, he was firmly opposed to violence in the anarchist cause.
