The Forests of Mara and Mondrem were adjacent medieval forests in Cheshire, England, which in the 11th century extended to over 60 square miles (160 km²), stretching from the Mersey in the north almost to Nantwich in the south, and from the Gowy in the west to the Weaver in the east. Mara and Mondrem were a hunting forest of the Norman Earls of Chester, established soon after 1071 by the first earl, Hugh d'Avranches. They might earlier have been an Anglo-Saxon hunting forest.
