The Six Corps was a 74-gun ship of the line of the French Navy. She was funded by a don des vaisseaux donation from the six corps that regrouped the merchants of Paris. Six Corps was built in Lorient on plan by engineer Groignard. After her completion, she was commissionned under Captain de Choras, and departed Lorient on 13 September 1763, bound for Brest, where she arrived on 27. Six Corps was then put in the reserve fleet, and never took part in any military operation. She was refitted in 1775, struck in 1779, and broken up the next year.
