The Spithead and Nore mutinies were two major mutinies by sailors of the Royal Navy in 1797. They were the first in an increasing series of outbreaks of maritime radicalism in the Atlantic World. Despite their temporal proximity, the mutinies differed in character. The Spithead mutiny was a simple, peaceful, successful strike action to address economic grievances, while the Nore mutiny was a more radical action, articulating political ideals as well, which failed.

The Channel Fleet and originally known as the Channel Squadron was the Royal Navy formation of warships that defended the waters of the English Channel from 1854 to 1909 and 1914 to 1915.
