Littlehampton is served by a mix of the major national supermarket chains, with a large Tesco Superstore and Morrisons on the edges of town, a Lidl close to the town centre, and smaller convenience-format branches in the High Street and Wick.

The nearest branches of some other national chains, including Aldi, Waitrose and Sainsbury's, are in neighbouring Rustington and Ferring rather than in Littlehampton itself, so they aren't listed here. Exact store locations, opening hours and services vary and change over time, so it's always worth checking directly with a store before a visit.
