Caludon Castle is a Scheduled Ancient Monument and Grade I listed building in Coventry, in the West Midlands of England. A second moated site to the south is a Scheduled Ancient Monument in its own right. The castle is now a ruin, and all that remains is a large fragment of sandstone wall. What remains of the estate is now an urban park, owned and run by Coventry City Council, but much of it was sold and developed into housing estates in the early 20th century.
