The Irish Land and Labour Association (ILLA) was a progressive movement founded in the early 1890s in Munster, Ireland, to organise and pursue political agitation for small tenant farmers' and rural labourers' rights. Its branches also spread into Connacht. The ILLA was known under different names—Land and Labour Association (LLA) or League (LLL). Its branches were active for almost thirty years, and had considerable success in propagating labour ideals before their traditions became the basis for the new labour and trade unions movements, with which they gradually amalgamated.

The Land Acts were a series of measures to deal with the question of tenancy contracts and peasant proprietorship of land in Ireland in the nineteenth and twentieth centuries. Five such acts were introduced by the government of the United Kingdom between 1870 and 1909. Further acts were introduced by the governments of the Irish Free State after 1922 and more acts were passed for Northern Ireland.
