What is now Centerport was originally inhabited by Matinecock Native Americans. In the 17th century, European colonists – primarily English along with some Dutch – began to settle the area. Suydam House, a saltbox house built in 1730, is one of the oldest surviving houses in Centerport. Camp Alvernia in Centerport was the first Catholic summer camp in the United States, established in 1888. The camp remained in operation as of 2026, serving over 900 local children aged 3–14 each summer. During the Gold Coast era, numerous wealthy individuals constructed large country estates in Centerport. Among the best-known examples of such estates in Centerport is the estate of William Kissam Vanderbilt II, known as Eagle's Nest; it is now the Vanderbilt Museum and Planetarium. In 1931, the portion of Centerport known as Little Neck proposed incorporating as a village; the proposed village was to be known as the Incorporated Village of Center Neck. The territory would have included several large estates – including the Vanderbilt estate. The proposal was defeated by residents of the proposed territory on October 24, 1931, by a vote of 49-to-40; many residents who opposed the plan feared that the proposed incorporation was an attempt by the community's large estate owners to more tightly regulate their properties and the local beaches for themselves. Accordingly, all of Centerport would remain an unincorporated hamlet within – and governed by – the Town of Huntington. The defeat of the incorporation proposal was met with a parade and celebration by opponents.

Formerly known as Little Cow Harbor in about 1700, as Centreport by 1836, and as Centerport after 1895, the community's name refers to its geographic position along the water, midway between the east and west boundaries of the Town of Huntington. The portion of the community known as Little Neck refers to its geographic location on the Little (Centerport) Neck. This peninsula's name, in turn, is derived from being the smaller of two adjacent "necks" – the other being known as Great (Northport) Neck.
