Hubbard Hall, also known as Kellogg House and Elizabethtown Community House, was a historic home located at Elizabethtown in Essex County, New York. It was a  2 1⁄2-story wood-frame building in the Queen Anne style. Hubbard Hall was originally built about 1840 as a typical five-by-two-bay Federal / Greek Revival–style structure and extensively remodeled in 1895. It featured multiple gables and dormers and interesting roof lines. A porch extended across three quarters of the front facade. In 1925 it was converted from a residence to a community hospital. A 2-story wing was added in 1946.
