East Rockaway is a village in Nassau County, New York, in the United States. The population was 9,818 at the 2010 census.
The Incorporated Village of East Rockaway is at the edge of Rockaway Peninsula Proper in the town of Hempstead, adjacent to Hewlett Harbor, Hewlett, Rockville Centre, Lynbrook, and Oceanside. It is the final neighborhood before the beginning of Five Towns, although some have come to include wealthier sections of East Rockaway as a part of Five Towns. The primary ethnicities are mainly Italian and Irish. The Waverly Park neighborhood, near the Hewlett-East Rockaway Jewish Center  and along the border with Hewlett, has a sizable Jewish community.
Originally named Near Rockaway, the village began as a shipping and trading center for the south shore of Long Island. The village's location was desirable for ships because of its deep channels inland. Eventually a grist mill was built on the Mill River by Joseph Haviland through a land grant in 1688. The Haviland-Davison Grist Mill, located in Memorial Park, was listed on the National Register of Historic Places in 1998. Later an oven was purchased to make bread for the surrounding population.
