Carleton St Peter is a hamlet[1] and civil parish in South Norfolk approximately 8+1⁄2 miles (13.7 km) south-east of Norwich.

There is no village centre but the church provides a reference point and is 1 mile (1.6 km) north-east of Thurton, and a similar distance south of Claxton, just east of Ashby St Mary.

In the 2001 census Carleton St Peter contained just 15 households and a population of 29 spread across the 3.19 km2 (1.23 sq mi) of the parish.

[4] The parish extends northwards to include the Beauchamp Arms public house on the south bank of the River Yare and the nearby Buckenham Sailing Club.

Between Carleton St Peter and Claxton, on the banks of Carleton Beck, lies Ducan's Marsh, a Site of Special Scientific Interest and one of the richest areas of unimproved wet grassland in East Norfolk.
