County Tipperary (Irish: Contae Thiobraid Árann) is a county in Ireland. Tipperary County Council is the local government authority for the county. Between 1898 and 2014 county Tipperary was divided into two counties, North Tipperary and South Tipperary, which were unified under the Local Government Reform Act 2014, which came into effect following the 2014 local elections on 3 June 2014. It is located in the province of Munster. The county is named after the town of Tipperary, and was established in the early thirteenth century, shortly after the Norman invasion of Ireland. The population of the entire county was 160,441 at the 2016 census. The largest towns are Clonmel, Nenagh and Thurles.

Tipperary is the sixth largest of the 32 counties by area and the 12th largest by population. It is the third largest of Munster's 6 counties by size and the third largest by population. It is also the largest landlocked county in Ireland. The region is part of the central plain of Ireland, but the diverse terrain contains several mountain ranges: the Knockmealdown, the Galtee, the Arra Hills and the Silvermine Mountains. Most of the county is drained by the River Suir; the north-western part by tributaries of the River Shannon; the eastern part by the River Nore; the south-western corner by the Munster Blackwater. No part of the county touches the coast. The centre is known as 'the Golden Vale', a rich pastoral stretch of land in the Suir basin which extends into counties Limerick and Cork.
