Cranwich is a village and civil parish in Norfolk, England.

Cranwich is located 8.6 miles (13.8 km) north-west of Thetford and 29 miles (47 km) west of Norwich.

Cranwich's name is of Anglo-Saxon origin and derives from the Old English for 'a marsh with cranes or herons.'

In the Domesday Book, Cranwich is listed as a settlement of 36 households in the hundred of Grimshoe. In 1086, the village formed part of the estates of William de Warenne.

In 1935, a labour camp was established in Cranwich by the Ministry of Labour for unemployed men. The camp gave manual work in forestry and quarrying and was closed at the onset of the Second World War, where it was used by the British Army.

In the 2011 Census, Cranwich's population is measured as a civil parish and therefore in the same survey as Ickburgh. The combined population of Ickburgh and Cranwich in 2011 was recorded as 309 residents living in 161 households.

Cranwich is located close to Watermill Broad and the course of the River Wissey. The A134, between King's Lynn and Colchester, runs through the village.

Cranwich's parish church is dedicated to Saint Mary and is one of Norfolk's 124 round-tower churches, dating from the 11th century. St. Mary's is located just off Cranwich Road and has been Grade I listed since 1960.
