Bay Saint Louis sits along the western shore of its namesake bay on Mississippi's Gulf Coast, carrying a history that stretches back to French colonial settlement and a cultural identity shaped by Creole heritage, Gulf breezes, and a deeply rooted arts community. As the county seat of Hancock County and part of the Gulfport-Biloxi metro area, the city punches above its weight for a community of roughly 25,000 residents. NASA's John C. Stennis Space Center lies just north, making it a quiet anchor for technical and government employment in the region. Historic Old Town draws people to its gallery-lined streets, including the Alice Moseley Folk Art and Antique Museum housed in the city's old train depot. Neighborhoods range from bayfront cottages and bungalows along Beach Boulevard to quieter residential streets set further inland. The rental market reflects that range, with single-family homes, townhomes, and small apartment communities offering options across different budgets. Daily life here moves at a measured pace, with public fishing piers, walkable stretches of downtown, and easy access to New Orleans less than an hour west making the location feel both removed from and connected to the wider Gulf South.

The GreatSchools Rating helps parents compare schools within a state based on a variety of school quality indicators and provides a helpful picture of how effectively each school serves all of its students. Ratings are on a scale of 1 (below average) to 10 (above average) and can include test scores, college readiness, academic progress, advanced courses, equity, discipline and attendance data. We also advise parents to visit schools, consider other information on school performance and programs, and consider family needs as part of the school selection process.
