County Offaly occupies a central position in Ireland's midlands. Its Irish name, Contae Uíbh Fhailí, recalls the early medieval kingdom of Uí Failghe from which the modern county takes its name. Administratively it is one of the counties of Ireland; its location within the province is commonly described as part of Leinster and it is governed locally by Offaly County Council (county authority).

Geography and landscape. The county combines low-lying farmland and extensive peatlands, most notably the Bog of Allen. The River Shannon runs close to important heritage sites and forms part of Offaly's western margin. The county includes areas of rolling countryside and uplands such as the nearby Slieve Bloom foothills, producing a mix of agricultural, peat and recreational landscapes.

History and cultural heritage. Offaly's identity is shaped by early Christian foundations and later Gaelic lordships. Significant historical and archaeological locations include the monastic site of Clonmacnoise on the Shannon and the demesne of Birr Castle, known for its historic telescope and scientific collections. The county's past also reflects Tudor and later administrative changes that created the modern county framework.

Economy, transport and settlements

Traditionally the local economy balanced agriculture, peat extraction and small industry. Peat harvesting and the activities of Bord na Móna were important in the 20th century and have influenced land use and conservation efforts. Tullamore is the county town and commercial centre, with other notable towns such as Birr and Edenderry providing local services and cultural life. Rail and road links connect Offaly to larger cities, offering commuter and freight routes.
