Admiral John Surman Carden (15 August 1771 – 22 April 1858) was an officer of the British Royal Navy in the early nineteenth century. Although the majority of his service was against the French during the Napoleonic Wars, he is best remembered for the action of 25 October 1812, an engagement against a larger American frigate during the War of 1812 in which his ship HMS Macedonian was captured. Carden was criticised for the loss of his ship, specifically his handling of the vessel during the action. Following his defeat in October 1812 he never served again in an active capacity, but he remained in the Navy and continued to gradually rise though the ranks in retirement, eventually becoming a full admiral before his death in 1858.
