Denning is an isolated town in Ulster County, New York, United States. The population was 493 at the 2020 census.[2] The town is named after an early landowner, William Denning. Denning is located in the western part of the county, deep inside the Catskill Mountains. The location of the town in the Catskill State Park accounts in part for its low population.
