Tween Waters Inn Historic District, Historic district in Captiva, United States.

Tween Waters Inn Historic District is a National Register district at Captiva, Florida, in Lee County, established by F. Bowman and Grace B. Price in 1931 and expanded over the following 30 years. It was added to the National Register of Historic Places in 2011.

The site began in 1931 as a fishing village with modest structures. Over the following decades, it grew into a recognized resort destination and was listed on the National Register of Historic Places in 2011.

The district takes its name from the inn founded in 1931 by F. Bowman and Grace B. Price, who built it up over the next three decades. Visitors today see the inn and its cottage colony on Captiva, and the whole district was listed on the National Register of Historic Places in 2011.

The district lies on Captiva's narrow northern end, with the Gulf of Mexico on one side and Pine Island Sound on the other. The inn and cottage colony sit along Captiva Drive, the island's single main road, so arriving by car is straightforward. The site was listed on the National Register in 2011, and the historic core is compact enough to walk between the inn, the cottages and the Old Captiva House.

The grounds preserve original structures from its founding era as a 1931 fishing village. These scattered authentic buildings give visitors a direct sense of how life looked in those early days.
