Norwich Arts Centre is a live music venue, theatre and art gallery located in St Benedict's Street in Norwich, Norfolk, England. It has a capacity of 300 for standing music concerts and 120 for seated events.

In 1976, a group formed for the purpose of starting an alternative venue for the visual and performing arts in Norwich. With the help of Norwich City Council the venue was opened in 1977 in a former carpet factory on St Benedicts Street and named "Premises". It moved to its current site, St Swithin's Church, in 1980 and has remained there since.

The redundant church which houses the Norwich Arts Centre is dedicated to Saint Swithun and dates from 1349
