The Thémis was a 40-gun Coquille class frigate of the French Navy.
She took part in the Battle of Cape Finisterre and in the Battle of Trafalgar. After the battle of Trafalgar, she took Principe de Asturias in tow to safety in Cadiz.
In early 1808, she raided commerce with Pénélope and sailed to Toulon. From there, she was tasked to ferry supplies to Corfu, along with Pauline. She was trapped there and eventually seized by the British when they captured the island.
