Waterfront Park in Safety Harbor Florida large outdoor recreation picnic family area

Safety Harbor is a city on the west shore of Tampa Bay in Pinellas County, Florida, United States. It was settled in 1823 and incorporated in 1917. The city is located on the west side of Safety Harbor, a waterway connected to Tampa Bay. According to the U.S. Census Bureau, the city has a total area of 5.1 square miles (13 km2), of which 4.9 square miles (13 km2) is land and 0.1 square miles (0.26 km2) (2.57%) is water.

In 1528 Spanish explorer Pánfilo de Narváez landed in the area, followed by Hernando de Soto in 1539. Safety Harbor (formerly known as Worth's Harbor and Green's Springs) was first homesteaded by Count Odet Philippe, a French nobleman who is credited with introducing the grapefruit to Florida in 1823. The name Safety Harbor originated from the early 18th century, when pirates were a substantial influence in the area. Once ships reached this area of the bay, all threats from pirates were gone, and it was commonly referred to as a "Safe Harbor".

Safety Harbor is the home of the historic Espiritu Santo Springs, or "Springs of the Holy Spirit", a natural mineral spring. Its waters were given this name in 1539 by the Spanish explorer Hernando de Soto, who was supposedly searching for the mythical "Fountain of Youth". Prior to the Spanish exploration of Florida, the Tocobaga and Timuquan tribes are believed to have fished and bathed in the spring's waters.

In the twentieth century, Espiritu Santo water was bottled and sold commercially, and later a health spa and hotel were built over the springs. The Safety Harbor Resort and Spa, as it is now known, continues to be a prominent visitor attraction in Pinellas County. In 1964, the site was designated a Historical Landmark by the U.S. Department of the Interior and, in 1997, a Florida Heritage Landmark.
