Lilleshall Abbey was an Augustinian abbey in Shropshire, England, today located 6 miles (9.7 km) north of Telford. It was founded between 1145 and 1148 and followed the austere customs and observance of the Abbey of Arrouaise in northern France. It suffered from chronic financial difficulties and narrowly escaped the Dissolution of the Lesser Monasteries in 1536, before going into voluntary dissolution in 1538.
