The House of Councillors was the upper house of the National Assembly of the Republic of Korea during its Second Republic. The House of Councillors was established by the Constitution of the Second Republic of Korea, which established a bicameral legislature. Officially, a House of Councillors was provided for by the Constitution of the First Republic, but the House of Representatives acted as the only house in a unicameral legislature since the House of Councillors was not actually established.
