Lorrha (from Irish: Lothra) is a small village at the northern tip of County Tipperary, Ireland. It is located on a minor road between the R489 Birr to Portumna road and the N65 Nenagh to Portumna road about five kilometres (three miles) east of the point where the River Shannon enters Lough Derg.
In 843 a Norse expedition led by Turgesius raided Lorrha and neighbouring Terryglass. Close to an historic crossing point of the River Shannon, the area has a long history of bridges and ferry crossings. The present Portumna bridge dates from 1911  (opening section replaced October 2008 )
Lorrha has a rich ecclesiastical history evidenced by the ruins within the village. Beside the Roman Catholic Church (c. 1912), at the south of the village are the remains of a Dominican Friary founded in the 13th century by Walter de Burgh, Earl of Ulster. To the east of the village stands the Church of Ireland  on the site of St. Ruadhan's church which was built c. 1000 AD and was itself built on the site of St. Ruadhan's Abbey, founded in the 6th century. Remains of two 8th-century high crosses stand in the churchyard. The Augustinian Abbey founded in the 12th century by the Order of Canons Regular stands nearby. The carved head over the door is thought to represent the wife of Walter De Burgh. Water for the monastic settlement was supplied from St. Ruadhan's well located south of the road that passes the present Church of Ireland cemetery.
