Count Honoré Joseph Antoine Ganteaume was a French Navy officer and Vice-admiral.

Ganteaume's expeditions of 1801 were three connected major French Navy operations of the spring of 1801 during the French Revolutionary Wars. A French naval squadron from Brest under Contre-amiral Honoré Ganteaume, seeking to reinforce the besieged French garrison in Ottoman Egypt, made three separate but futile efforts to reach the Eastern Mediterranean. The French army in Egypt had been trapped there shortly after the start of the Napoleonic campaign in Egypt in 1798, when the French Mediterranean Fleet was destroyed at the Battle of the Nile. Since that defeat, the French Navy had maintained only a minimal presence in the Mediterranean Sea, while the more numerous British and their allies had succeeded in blockading and defeating several French bases almost unopposed.
