**History**
Established in 1739 as Millville, Yaphank's development was closely tied to the Carmans River, which provided water power for mills and served as a transportation route. The arrival of the railroad in 1844 spurred further growth, leading to the renaming of the community to Yaphank, derived from the Algonquin language, likely meaning "open land" or "place of the open field."
