'''Cowpen Marsh''' ({{gbmapping|NZ500529}}) is a 116.8 [[hectare]] [[biological Site of Special Scientific Interest]] in [[County Durham]], [[England]], [[SSSI notification|notified]] in 1966.  SSSIs are designated by [[Natural England]], formally [[English Nature]], which uses the [[Metropolitan and non-metropolitan counties of England|1974–1996 county system]]. This means there is no grouping of SSSIs by [[Stockton-on-Tees (borough)|Stockton-on-Tees]] unitary authority, or County Durham which is the relevant [[Ceremonial counties of England|ceremonial county]] . As such Cowpen Marsh is one of 18 SSSIs in the [[List of Sites of Special Scientific Interest in Cleveland|Cleveland area of search]].<ref>{{cite web | title=SSSIs in Cleveland area of search | url=http://www.english-nature.org.uk/special/sssi/searchresults.cfm?sssi_name=&frmcounty=1007 | work=English Nature | accessdate=31 January 2007}}</ref>
