Rhosybol is a village and community in Anglesey, Wales. The community population at the 2011 census was 1,078. Located 2.5 miles (4.0 km) south of the town of Amlwch, the village is close to both Llyn Alaw, the largest body of water on the island, and Parys Mountain, the site of the historic copper mines which lies just to the north. It is to the mines that the village owes its existence as it was one of several built to house the miners. During the 1960s noted painter Kyffin Williams produced an oil painting of the village.
