East Moriches (/moʊˈrɪtʃɪz/ ⓘ moh-RITCH-iz)[2] is a hamlet and census-designated place in the Town of Brookhaven, Suffolk County, New York, United States near the south coast of Long Island.

Once a student graduates 8th grade, they may choose to attend one of three high schools; Westhampton Beach, Center Moriches, or Eastport-South Manor.

East Moriches became known internationally on July 17, 1996, when TWA Flight 800 exploded 8 miles (13 km) off the coast and fell into the Atlantic Ocean.

The U.S. Coast Guard Station, East Moriches, was used by emergency responders, and was the site where the bodies were initially prepared for transport.

Today there are parks in Smith Point and Center Moriches on Long Island, New York dedicated to those who died in the crash, and a plaque bearing their names.
