Bainbridge Island is eleven miles long and four miles in average width between Port Orchard Bay on the west and Puget Sound on the east in east central Kitsap County. Capt. George Vancouver sighted it, but did not recognize it as an island. Cmdr. Charles Wilkes discovered that it was an island when he traversed Agate Pass, and named it for Capt. William Bainbridge a naval hero of the War of 1812. The island had a prominent timber and agricultural history, though it is now largely residential.
