Otsego Hall was a house in Cooperstown, New York, United States, built by William Cooper, founder of the town.

For many years, it was the manor house of Cooper's landed estate, and was one of the largest private residences in central New York.

In June 1834, James Fenimore Cooper resolved to reopen the house after an absence of nearly sixteen years.

In this, Cooper was assisted by his friend, Samuel F. B. Morse, a painter and inventor, who designed two towers for the front and east sides of the structure.

[2] At first, Cooper spent his winters in New York City and summered in Cooperstown, but eventually he made Otsego Hall his permanent abode.
