Auguste was an 80-gun ship of the line in the French Navy, laid down in 1777 and in active service from 1779.

Soon after her commissioning, from June to September 1779, Auguste patroles the Channel under Captain de Rochechouart.

The next year, she took part in the Combat de Prairial, where she followed the flagship Montagne, and failed to prevent HMS Queen Charlotte from breaking the French line.

On 29 January, as she took part in the Croisière du Grand Hiver, she was caught in a tempest off Brest and wrecked with the loss of most of her crew.
