Rosside is a small village in Cumbria, England, on the outskirts of Ulverston. The village consists of around 15 houses, all contained in an area of around 600 square metres (6,500 sq ft). Rosside is part of the Ulverston parish, as are the neighbouring villages of Pennington, Swarthmoor and Loppergarth.
