Jacques-Noël Sané (18 February 1740, Brest – 22 August 1831, Paris) was a French naval engineer.
He was the conceptor of standardised designs for ships of the line and frigates fielded by the French Navy in the 1780s, which served during the French Revolutionary Wars and the Napoleonic Wars and in some cases remained in service into the 1860s.
Captured ships of his design were commissioned in the Royal Navy and even copied.
His achievements earned Sané the nickname of "naval Vauban"
