St. Georg is a Lutheran parish church in Brockhagen, now part of Steinhagen, North Rhine-Westphalia, Germany.

The aisleless church has a west steeple dated 1568, with four storeys.

The altar is dated 1675 and features two oil paintings, showing The Last Supper and the Resurrection of Jesus.

The organ, possibly built by Hans Henrich Reinking, was installed in 1661.

The church interior was restored over eight months in 2017, including new lighting, more flexible seating by replacing some benches with chairs, and a new heating system.
