Invincible was a first-rate ship of the line of the French Royal Navy.

Built on plans by Francois Guillaume Clairin Deslauriers at Rochefort as part of the French naval mobilisation for the American War of Independence, she was a sister-ship of Royal Louis.

(Comte de la Motte was her captain April 1781–April 1783).

She took part in the Battle of Cape Spartel, where she attacked the rear of the British squadron.

She was refitted several time (1781, 1784 and 1795) until her career came to an end in 1807 when she was disarmed and finally broken up in 1808 at Brest.
