Cobholm Island is situated in the East Anglian county of Norfolk, England, close to Great Yarmouth. The population of the Island is included in the Southtown and Cobholme Ward of Great Yarmouth Borough Council. Originally the island was bounded by the River Yare to the east, Breydon Water to the north, and the Lady Haven to the south and west. The latter has dried up following building, so Cobholm Island now directly connects to Southtown to the west of Great Yarmouth.
