Selden (historically known as Westfield) is a hamlet and census-designated place (CDP) in the Town of Brookhaven in Suffolk County, New York, United States.

[4] Roe is buried in a small family cemetery south of Middle Country Road behind the Old Westfield shopping center.

In the fall of 1776, Roe was assigned to lead a raid against the Tory and Hessian detachment near Selden led by his cousin Richard Miller.

[11] While some sources report that the attorney had no known connection to the community, one newspaper reported in 1858 that Selden and attorney Edward Boyle (the namesake for Boyle Road) acquired a large tract of land in the hamlet shortly before the post office opened, and started to develop it.

[12][13] As of 1885, Selden was home to 88 residents and a Presbyterian church (built in 1857), and noted for producing melons and early garden vegetables from its farms.

The location, including some of its original buildings, became in 1961 the main (Ammerman) campus of Suffolk County Community College, which today has an enrollment of over 11,000 students.

Similar to surrounding communities, Selden has a number of shopping centers along Middle Country Road,[22] which developed as suburban growth spread eastward.

In 1972, the first Westfield Shopping Center opened at the intersection of Middle Country and Blue Point roads, with a Hills Supermarkets location.

Its original anchor tenants included King Kullen, Builders Emporium, and Genovese Drug Stores.

This has significantly increased the popularity of "Downtown Selden" in the past few years attracting more local and national chain businesses.

[27] According to the United States Census Bureau, the CDP has a total area of 4.3 square miles (11.2 km2), all land.
