Liverpool Castle in Liverpool, England was probably erected in the 1230s, between 1232 and 1237 under the orders of William de Ferrers, Earl of Derby. The castle was built to protect King John's new port of Liverpool and was sited at the present day Derby Square (Queen Victoria Monument) near the city centre - then a prominent site overlooking the River Mersey. The modern-day lawcourts on the site were built in the style of a castle. The castle was ruined during the English Civil War and completely demolished in the 18th century.

In the village of Rivington on the West Pennine Moors near Chorley there is a rebuild of Liverpool Castle.
