The Battle of Castlehaven was a naval battle that took place on 6 December 1601 in the bay off Castlehaven on the south coast of Ireland during the Nine Years' War between a Spanish naval convoy of six ships and an English fleet, commanded by Admiral Richard Leveson and consisting of four warships. The Spanish convoy was protected by fortified positions on shore, a castle, and 600 Spanish and Irish footmen. Five out of six Spanish ships, commanded by General Pedro de Zubiaur were either sunk, captured, or run aground in the battle, while the English fleet lost no ships.
