Lewis's is an online retailer and homeware brand. It was also a chain of British department stores that operated from 1856 to 2010. The owners of Lewis's went into administration several times, including in 1991. The first store, which opened in Liverpool city centre, became the flagship of the chain. Several stores in the chain were bought in 1991 by the company Owen Owen and continued to operate under the Lewis's brand name for several years, but after the closure of the Manchester store in 2001, only the original Liverpool store continued to trade under the Lewis's name. This store was sold in 2007 to Vergo Retail Ltd and closed in 2010.

A department store is a retail establishment offering a wide range of consumer goods in different areas of the store, each area ("department") specializing in a product category. In modern major cities, the department store made a dramatic appearance in the middle of the 19th century, and permanently reshaped shopping habits, and the definition of service and luxury. Similar developments were under way in London, in Paris and in New York City (Stewart's).
