The John Lewis Partnership plc (JLP) is a British company that operates John Lewis & Partners department stores, Waitrose & Partners supermarkets, its banking and financial services, and other retail-related activities. The privately-held public limited company is owned by a trust on behalf of all its employees – known as partners – and a bonus, akin to a share of the profit, is paid to employees. John Lewis has around 80,800 partners/employees as of 2020. JLP Group was the third-largest UK non-traded company by sales in The Sunday Times Top Track 100 for 2016. The chain's image is upmarket, and its customers are likely to be more affluent consumers. It was a member of the International Association of Department Stores from 2004 to 2010.

The Partnership also supplied the Ocado web supermarket with Waitrose own-brand foods and John Lewis own-brand non-food items such as furniture. This arrangement expired in September 2020, when Marks & Spencer began a new £750 million contract with Ocado.
