The Seattle–Bainbridge ferry is a ferry route across Puget Sound between Seattle and Bainbridge Island, Washington. The route was called the Seattle–Winslow ferry before the city of Winslow annexed the rest of the island and changed its name. Since 1951 the only ferries employed on the route have belonged to the Washington state ferry system, currently the largest ferry system in the United States. The Seattle–Bainbridge Island route is the busiest in the system and was used by over 4.9 million total passengers in 2024.
