The Shannon SH 1 was a racecar which was designed by Hugh Aiden-Jones and raced during two races in the 1966 season of Formula One.

The car made its debut at the 1966 British Grand Prix where it was being driven by Trevor Taylor. The car started in 18th on the grid but was retired from the race due to a tank issue.

The car was then entered in a second race, the 1966 Italian Grand Prix. The engine was changed to a Climax FWMV V8 but this proved disastrous as the car was unable to race due to engine problems.

At the British Grand Prix, the car was fitted with a Climax FPE V8 engine. For both races the car was entered in, it rode on Dunlop Tires. The car had an aluminium monocoque chassis.
