Dunedin is a city in Pinellas County, Florida, United States. The name comes from Dùn Èideann, the Scottish Gaelic name for Edinburgh, the capital of Scotland. Dunedin is part of the Tampa–St. Petersburg–Clearwater metropolitan area and is the fifth largest city in Pinellas County. The population was 36,068 as of the 2020 census.

Dunedin is home to several beaches, including Dunedin Causeway, Honeymoon Island, and Caladesi Island State Park, which is consistently rated among the best beaches in the world. Dunedin is one of the few open waterfront communities from Sarasota to Cedar Key where buildings do not completely obscure the view of the Intracoastal Waterway and the Gulf of Mexico beyond; a 1-mile (1.6 km) stretch of Edgewater Drive (also known as Alternate US 19) south of downtown offers views of St. Joseph Sound, Clearwater Beach, and Caladesi Island. Downtown Clearwater and Clearwater Beach are a 6-mile (10 km) drive south on Edgewater.
