The 1899 Irish local elections were the first local elections following the reorganisation of Irish local government caused by the Local Government (Ireland) Act 1898. The 1898 Act had changed the nature of Irish local governance, replacing the unrepresentative grand jury system, and making local government more democratic and representative. As a result, the 1899 election saw the traditional Unionist Landowning class, which had previously dominated much of Irish local politics, being replaced by a newer nationalist representation. Ulster's local government, however, remained Unionist in political outlook.
