Middle Island is a hamlet and census-designated place (CDP) in the Town of Brookhaven, Suffolk County, New York, United States.

[2] It is situated between the hamlets of Coram and Ridge, to the west and east, respectively, and Rocky Point and Yaphank to the north and south.

The name derives from the fact that it lies approximately halfway between the eastern and western ends of Long Island (Montauk Point and the East River) as well as halfway between the northern and southern boundaries (the Long Island Sound and the Atlantic Ocean).

David Rose, who was also a doctor and a pastor of the South Haven church,[3] covered his immense parish on horseback.

Around the same time, a veteran of the French and Indian War named Jonathan Edwards who admired the white pine trees of Quebec swiped the seedlings for himself and began planting them along what is today Middle Island-Miller Place Road.

For over 100 years (until it was burned down in 1971), Pfeiffer's Store was a center of activity for Middle Island and surrounding communities.

On October 27, 1910, the International Aviation Tournament was held at the Belmont Park racetrack in Elmont, New York.

Middle Island gained an influx of Estonian refugees during the 1940s and 1950s mainly around the Pine Lake area.
