The Penrith Co-operative Society Limited, known locally as Penrith Co-op, is a small regional consumer co-operative in the United Kingdom. The society was formed in 1890 and today operates one department store with supermarket attached and eight small supermarkets or convenience stores in Cumbria and County Durham.When most other co-operatives in Cumbria merged into regional groups in the 1960s and 1970s, such as the Cumbrian Society and the Greater Lancastria Society (now both part of The Co-operative Group), the Penrith society remained independent and has since taken over other small societies.
