The Vanwall VW 55 was a racecar designed by Owen Maddock.

The car made its debut at the 1955 Monaco Grand Prix being driven by Mike Hawthorn. The car did not finish the race due to throttle problems. Other drivers throughout the 1955 Forumla One Season included Harry Schell and Ken Wharton.

The cars had a Vanwall 254 L4 engine and rode on Pirelli tyres.

The VW55 did not endure good success with one car only finishing one of the races it entered. During the other races the cars were retired due to mechanical problems or driver injury.
