The Battle of Cádiz (1640) was a naval battle in the Franco-Spanish War (1635-1659), which took place on July 21, 1640, when a French squadron under Jean Armand de Maillé-Brézé attacked a Spanish convoy coming from the Americas.

The attack occurred just in front of the coast of Cádiz. Armand de Breze employed a hitherto unknown tactic to attack the Spanish convoy from both sides. The Spanish lost a galleon and a small vessel but the convoy completed its journey and delivered most of its cargoes including its silver bullion. French losses are unknown.
