About Islandia

Tucked into central Suffolk County, Islandia is a small, quiet Long Island village with a population of around 3,500. Sitting right along the Long Island Expressway, it offers a straightforward commute east or west across the island. The community consists mostly of peaceful residential streets, with easy access to shopping centers, restaurants, and major job centers in neighboring towns like Hauppauge and Central Islip.

Green space is a major highlight for residents, with over 275 acres of preserved county parkland weaving right through the area. Spots like Lakeland Park and the village recreation fields give locals plenty of room for morning walks, youth sports, and afternoons at the playground. If you are moving with school-aged children, keep in mind that district boundaries vary by neighborhood, zoning students into the Central Islip, Hauppauge, or Connetquot school systems depending on your exact address.
