East Williston is an incorporated village in the Town of North Hempstead in Nassau County, on Long Island, in New York, United States.

The original borders of the area known as East Williston stretched west towards Queens to Herricks Road, north to I.U.

Henry M. Willis designed and built the popular East Williston Runabout Roadcart.

Its soft suspension allowed comfortable travel over the rough roads of the time.

Over 1,000 East Williston Runabout Roadcarts were built by Oakley and Griffin (who purchased the business from Willis in 1889).

[5] Since there was already a community with a post office in Upstate New York using the name, locals added the word "East" to their community's name; the name East Williston was in use for both this village and what is now the adjacent village of Williston Park.

[5] According to the United States Census Bureau, the village has a total area of 0.6 square miles (1.6 km2), all land.

[7][22] East Williston is located entirely within New York's 3rd Congressional district, which as of August 2024 is represented in the United States Congress by Thomas R. Suozzi (D–Glen Cove).

[7][23] Like the rest of New York, East Williston is represented in the United States Senate by Charles Schumer (D) and Kirsten Gillibrand (D).

[24] In the 2020 U.S. presidential election, the majority of East Williston voters voted for Donald J. Trump (R).
