The name of the cars and boats in which father and son Sir Malcolm Campbell and Donald Campbell have set the world records for speed on land and on water.

Malcolm Campbell took the name for his car after seeing Maeterlinck's play The Bluebird. He exceeded 300 mph on 3 September 1935

Donald Campbell died in his Bluebird K7 on 4 January 1967, on Coniston Water in Cumberland, at the age of 46. The Bluebird has just been rediscovered by divers and filmed by a BBC crew; it was raised on 8 March 2001.

He reached over 300 mph on his first pass, then turned around, but he had not waited for his wake to settle. The Bluebird hit it and somersaulted catastrophically.

Bluebird Electric is the name of a modern British contender for the land speed record for electric cars, driven by Donald's nephew Don Wales.
