Samuel Hayes (born circa 1748, died August 1821) was an early American settler, primarily known for his role in the establishment and development of the Western Reserve in present-day Ohio. Hayes migrated from Granby, Connecticut to the Western Reserve in 1799, becoming one of the first permanent settlers in what is now Trumbull County. He played a significant role in the early governance and organization of the region.
Hayes served as a judge, a state legislator, and was active in local militia activities. He also operated a grist mill and a sawmill, contributing to the economic infrastructure of the developing settlement. His family was among the earliest to establish a presence in the area, enduring the hardships and challenges of frontier life. Hayes is remembered as a key figure in the early history of northeastern Ohio and the expansion of the United States westward. He is buried in the churchyard in Kinsman, Ohio.
