The Thomas Cole National Historic Site, also known as Cedar Grove, is a National Historic Landmark that includes the home and the studio of painter Thomas Cole, founder of the Hudson River School of American painting. It is located at 218 Spring Street, Catskill, NY, United States. The site provided Thomas Cole with a residence and studio from 1833 through his death in 1848.

Thomas Cole was an English-born American artist and the founder of the Hudson River School art movement. Cole is widely regarded as the first significant American landscape painter. He was known for his romantic landscape and history paintings. Influenced by European painters, but with a strong American sensibility, he was prolific throughout his career and worked primarily with oil on canvas. His paintings are typically allegoric and often depict small figures or structures set against moody and evocative natural landscapes. They are usually escapist, framing the New World as a natural eden contrasting with the smog-filled cityscapes of Industrial Revolution-era Britain, in which he grew up. His works, often seen as conservative, criticize the contemporary trends of industrialism, urbanism, and westward expansion.
