Bruix' expedition of 1799, often called Croisière de Bruix in French sources, was a French naval operation of the French Revolutionary Wars, carried out in May 1799 by Vice-admiral Bruix. It aimed at sending the naval squadron of Brest to the Mediterranean, gathering Spanish ships on the way, and rescuing Malta and Corfu, and supporting the French armies in Italy. The actual objectives of the expedition remain unclear.
