Blue Bird K4 was a powerboat commissioned in 1939 by Sir Malcolm Campbell, to rival the Americans' efforts in the fight for the world water speed record.
The name "K4" was derived from its Lloyd's unlimited rating, and was carried in a prominent circular badge on the forward hull. As this was Campbell's second boat, it was also known as Blue Bird II. He used the name for a series of land speed record cars, his record boats and also his motor yacht.[i]

K4 was built by Vosper & Company as a replacement for Blue Bird K3, which had set three other water speed records for Malcolm Campbell before the K4 was built. It also used the same Rolls-Royce R engine.
