Arun Yacht Club is a family-focused community sailing club founded in 1956, situated on the west bank of the River Arun in Littlehampton, West Sussex.

Run by volunteer members, it serves as a base for both dinghy and cruiser sailing, with access to the open sea via a short sail through Littlehampton Harbour's arms. Dinghies launch from a secure compound over a firm, sandy beach directly into the River Arun.

The club runs a year-round racing programme, with sea sailing from Easter to Christmas and river sailing during the winter months.

Visiting yachts are welcomed and can take to the mud on spare marina berths, though advance arrangements are recommended; the club does not accept visiting motorboats.
