Bell Island, island in southeastern Newfoundland, Canada; it lies in Conception Bay 3 mi (5 km) off the Avalon Peninsula. Bell Island is 6 mi long and 3 mi wide, and has an area of 11 sq mi (28 sq km). Named after a large bell-shaped rock off its west end, it was one of the world’s major iron-ore producers from 1895 to 1966. Fishing and subsistence agriculture are now the main economic activities on the densely populated island. Regular ferry service connects Wabana, its largest town, with the Avalon Peninsula.
