The Battle of Bonchurch took place in late July 1545 at Bonchurch on the Isle of Wight. No source gives the precise date, although 21 July is possible from the sequence of events. The battle was a part of the wider Italian War of 1542–1546, and took place during the French invasion of the Isle of Wight. Several landings were made, including at Bonchurch. Most accounts suggest that England won the battle, and the French advance across the island was halted.
