Rosemary Beach is an unincorporated planned community in Walton County, Florida, United States on a beach side road, CR 30A, on the Gulf Coast. Rosemary Beach is developed on land originally part of the older Inlet Beach neighborhood. The town was founded in 1995 by Patrick D. Bienvenue, President of Leucadia Financial Corporation, and was designed by Duany Plater-Zyberk & Company. The town is approximately 105 acres (0.42 km) and, upon completion, included more than 400 home sites and a mixed-use town center with shops, restaurants, and activities.

The design of the town reflects the French Quarter in New Orleans. Rosemary Beach was named after Rosemary Milligan, a realtor and entrepreneur, who inhabited the area since 1974 and owned much of the land that is now Rosemary Beach before selling the property to developers. The town is also rumored to be named after the fresh rosemary growing in the area.

Rosemary Beach is one of three planned communities on Florida's Gulf coast designed by Andrés Duany and Elizabeth Plater-Zyberk. The other two are Seaside and Alys Beach. The three are examples of a style of urban planning known as New Urbanism.

Rosemary Beach, designed in 1995, offers shops, restaurants, a hotel, and public green spaces. The design of the town reflects New Orleans’ French Quarter and European Colonial influences in the West Indies and Caribbean. Sustainable materials, natural color palettes, high ceilings for better air circulation, balconies, and easy access to the beach by foot are typical design features.

The architecture of the homes in Rosemary resemble places like New Orleans, St. Augustine, Charleston S.C., and the West Indies. The houses along Rosemary Beach are close together and are all neutral colored. The community has four open door swimming pools.
