French ship Union (1764)

The Union was a 64-gun ship of the line of the French Navy. She was funded by a don des vaisseaux donation from individuals.

The construction of Union, initially ordered in 1755, dragged on until 1763. In 1767, she cruised off Morocco under Captain de Breugnon.

In 1778, she was converted into a hospital ship and was appointed to a squadron under Admiral d'Orvilliers. She was eventually wrecked in February 1782
