Put-in-Bay is a village located on South Bass Island in Put-in-Bay Township, Ottawa County, Ohio, United States. Many believe that the name originates from some early maps of South Bass Island that showed the harbor being named Pudding Bay, probably because it was shaped like a pudding sack. The population was 128 at the 2000 census. The village played a significant role in the War of 1812 as the location of the squadron of U.S. naval commander Oliver Hazard Perry, who sailed from the port on September 10, 1813 to engage a British squadron just north of the island in the Battle of Lake Erie. The village is a popular summer resort and recreational destination. Ferry service connects the community with Catawba Island, Kelleys Island, Port Clinton, and Sandusky, Ohio.
