Homer is a village in Cortland County, New York, United States. The population was 3,291 at the 2010 census. The village name is derived from the surrounding town, which was named after the poet Homer.
Homer is in the former Central New York Military Tract and was within a Military Tract township which was assigned the name "Homer" by a clerk.
Amos Todd, his sister Rhoda Beebe, and her husband Joseph Beebe founded the community in 1791. The village was incorporated in 1835.
The town was the inspiration for "Homeville", the small town in the novel David Harum by Edward Noyes Westcott.
