Peterborough Guildhall is a municipal building in Cathedral Square, Peterborough, Cambridgeshire, England. It is a Grade II* listed building.

The current structure replaced a medieval guildhall which was situated on the northern side of Cathedral Square. The local people decided to erect a new structure to commemorate the restoration of the monarchy in 1660. The site selected for the new building had previously been occupied by the "Butter Cross" or dairy market.
