Mossbank is a village in the north east of the Mainland of Shetland, Scotland. Originally served by an inter island ferry steamer from Lerwick, this ceased when the Yell Sound ferry commenced from the small port of Toft, approximately 1 mile further north. The village was profoundly changed in the early 1980s when construction began on the nearby Sullom Voe oil terminal. Large amounts of temporary accommodation were erected to house the construction workforce, with the population expanding from 130 in the early 1970s to about a thousand a decade later. The number of residents staying in Mossbank is forever changing, making it hard to record a village population.
