The town of Hamlin occupies the northwest corner of Monroe County. It is bounded on the west by the town of Kendall, Orleans County, on the north by Lake Ontario, on the east by Parma, and on the south by its parent, Clarkson. It is the county's second largest town with a land area of 44.4 square miles (26.387 acres). Although it contains no incorporated villages, six active hamlets are part of its history: two bisected by the county line: Morton and Kendall Mills; three straddling Lake Road in the center of town: North Hamlin (Thomasville), Hamlin Station, and Hamlin Center; and Walker, in the town's eastern section.
