Córas Iompair Éireann (Irish for Irish Transport Company), or CIÉ, a statutory corporation of Ireland, is founded on January 1, 1945. CIÉ is answerable to the Irish Government and responsible for most public transport within the Republic of Ireland and jointly with its Northern Ireland counterpart, the Northern Ireland Transport Holding Company for the railway service between the Republic of Ireland and Northern Ireland. The company is headquartered at Heuston Station, Dublin. Its members are appointed by the Minister for Transport.

Córas Iompair Éireann is formed as a private company by the Transport Act 1944 and incorporates the Great Southern Railways Company and Dublin United Transport Company, initially adopting the logo of the latter company. Great Southern Railways (GSR) is incorporated in 1925, having been Great Southern Railway since 1924. Essentially the GSR becomes – especially as it starts to broaden its business interests into road transport – a monopoly transport operator. The Transport Act 1950 amalgamates CIÉ and the Grand Canal Company and formally nationalises CIÉ, changing its structure from that of a private limited company to a corporation under a board appointed by the Minister for Transport. The Northern Ireland Great Northern Railway Act, 1958 transfers the lines of Great Northern Railway Board south of the border to CIÉ. Until 1986 CIÉ operates as a single legal entity, although it is internally organised into rail services and two bus divisions – Dublin City Services and Provincial Services. The vast majority of services are branded CIÉ, although long-distance provincial buses are branded “Expressway” and Dublin electric trains DART. In 1987, CIÉ reorganises into a holding company and three operating companies. In 1990 it sells its nine Great Southern Hotels, including its hotel in Derry, Northern Ireland, to Aer Rianta, the airports authority.

Since the enactment of the Transport (Re-organisation of Córas Iompair Éireann) Act, 1986 CIÉ has been the holding company for Bus Éireann, Dublin Bus and Iarnród Éireann/Irish Rail, the three largest internal transport companies in Ireland. It was originally to have operated the Luas tram system in Dublin, but that project was transferred to the newly created Railway Procurement Agency.

CIÉ is responsible for the overall strategy of the group. It owns all fixed assets used by the three companies, such as railway lines and stations, the latter being dealt with through the Group Property division. It also operates an international tour division, CIÉ Tours International. CIÉ’s vast number of advertising sites are organised through Commuter Advertising Network (CAN), since the mid-1990s employing an external company (currently Exterion Media Ireland) to manage them. There are also a number of shared services provided by CIÉ to its three operating companies.

Other than in the railway sector CIÉ is not a monopoly provider of public transport services as a number of other operators exist. However, under the Transport Act, 1932, these may not compete directly on any route for which CIÉ has been granted a licence. Legislation is enacted in 2013 to provide for the tendering of 10% of routes operated by Dublin Bus and Bus Éireann. This public competition includes these two operators, along with private operators such as Go-Ahead Ireland, and is completed in January 2019.
