Islandia is a village in the northern part of the Town of Islip in Suffolk County, on Long Island, in New York, United States.

[2][3] After more than three years of conducting local research, residents appeared in front of Islip's officials to take the first steps in incorporating Islandia on September 16, 1980.

[3][4] The core of Islandia is a 500-home housing development built by Levitt & Sons circa 1963, which offered seven different model homes to choose from.

[4] The original Levitt home buyers were informed during pre-construction sales that their children should attend the Hauppauge Union Free School District, but instead it became part of the Central Islip Union Free School District.

[8][9] These plans attracted opposition from some members of the community citing possible crime and traffic problems, while others supported the first new casino to be opened in Suffolk County.

[9] According to the United States Census Bureau, the village has a total area of 2.2 square miles (5.7 km2), all land.

Honeysuckle Pond, in Suffolk County's Lakeland Park, lies within the confines of the Village and is thus included in its geographic makeup.

[10][11] In the latter half of 2016 and the majority of 2017, the pond was virtually nonexistent, reduced to a muddy puddle devoid of wildlife.

As of 2000, Islandia had the highest percentage of Turkish residents in the United States, at 2.5% of the village's population.
