Shoreline Park is a former census-designated place (CDP) in Hancock County, Mississippi.

The area is now largely within the city limits of Bay St. Louis, although some of the western side of the former CDP is still unincorporated after Hurricane Katrina in 2005.

As of the census[3] of 2000, there were 4,058 people, 1,649 households, and 1,119 families residing in the CDP.

25.2% of all households were made up of individuals, and 6.7% had someone living alone who was 65 years of age or older.

The former Shoreline Park CDP is divided between the Bay St. Louis-Waveland and Hancock County school districts.
