Tidewater Region

Tidewater is a region in the Atlantic Plains of the United States located east of the Atlantic Seaboard fall line (the natural border where the tidewater meets with the Piedmont region) and north of the Deep South. The term "tidewater" can be applied to any region where water levels are affected by the tide. Still, culturally and historically, the Tidewater region refers most commonly to the low-lying plains of southeastern Virginia (known as the coastal plain or Tidewater Virginia), eastern Maryland, the Eastern Shore, and the Chesapeake Bay. It can also encompass Delaware, the remainder of the Delmarva Peninsula, and Northeastern North Carolina.

The cultural Tidewater region got its name from the effects of changing ocean tides on local rivers, sounds, and shorelines. The area has a centuries-old cultural heritage that sets itself apart from the adjacent inland parts of the United States, especially concerning its distinctive dialects of English, which are gradually disappearing, along with its islands and its receding shoreline.
