British Queen was a British passenger liner that was the second steamship completed for the transatlantic route when she was commissioned in 1839. She was the largest passenger ship in the world from 1839 to 1840. She was named in honor of Queen Victoria and owned by the British and American Steam Navigation Company. British Queen would have been the first transatlantic steamship had she not been delayed by 18 months because of the liquidation of the firm originally contracted to build her engine.
