The Battle of Bonchurch took place sometime in late July 1545 at Bonchurch on the Isle of Wight. No source of information states a specific date, although it could have happened on 21 July. The battle was a part of the wider Italian War of 1542–1546, and the battle took place during the 1545 French invasion of the Isle of Wight. Several landings were made by the French during the invasion of the Isle of Wight, including the one at Bonchurch. The two combatants were the Kingdom of England and France. England won the battle, and the French advance across the Isle of Wight was halted.
