The Land Law (Ireland) Act 1881 was the second Irish land act passed by the Parliament of the United Kingdom.

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.
