The Fleet Air Arm Museum is offering locals a 30 per cent discount on year-long entry.
The offer, which starts on November 4, is available for people with BA, TA, DT, SP, and BS postcodes.
It is valid until February 14, and the tickets allow unlimited visits for a year.
The museum, home to Europe's largest naval aircraft collection, has more than 100 aircraft, two million records, artefacts, and objects.
Marc Farrance, Fleet Air Arm Museum general manager, said: "This is the third year of the scheme and it’s always a joy to offer reduced entry to those who live locally.
"Now is the perfect time to visit and see some of your favourite aircraft or exhibitions, or experience it all for the first time.
"The discounted tickets represent great value, offering a whole year of access, and come just as many of us are looking for Christmas gifts."
Visitors can enjoy the Barracuda Live: The Big Rebuild project, aiming to build the only complete Fairey Barracuda in the world, and the updated Aircraft Carrier Experience.
The discount can be redeemed online by inputting your billing address, or in person by bringing proof of address.
