St George's Church is an Anglican church in the Kemptown area of Brighton, in the English city of Brighton and Hove. It was built at the request of Thomas Read Kemp, who had created and financed the Kemp Town estate on the cliffs east of Brighton in the early 19th century, and is now regarded as the parish church of the wider Kemptown area.

The church has a community centre at which various groups meet regularly, and a café, in the crypt below the building. The café is operated in partnership with a local special school. The crypt facilities were built (along with some supporting structural work for the rest of the church) with support from the European Union's "URBAN" regeneration fund, for which they had to compete with other local projects.

St George's also acts as one of Brighton's largest venues for alternative and folk music concerts.
