The Belfast Labour Party was a political party in Belfast, Ireland from 1892 until 1924. The first socialist party in Ireland, it was founded in 1892 by a conference of Belfast Independent Labour activists and trade unionists. The party affiliated itself to the British Labour Representation Committee in 1900 and remained attached to its successor; the UK Labour Party. Labour ran the Unionist Party close in Belfast North in a by-election in 1905 and in the general election of 1906 with William Walker as its candidate.
