St Peter's Church, Sudbury is a former Anglican church in the town of Sudbury, Suffolk, England, which now serves as a cultural venue. The building is recorded in the National Heritage List for England as a designated Grade I listed building, and is under the care of the Churches Conservation Trust. The building stands in the heart of the town in a dominating position on Market Hill. A church has been on the site since at least 1180, but the current structure dates from the 15th century, though there have been several restorations in the intervening period.
