The Morgan Mansion is a historic residence in and the current city hall of Wellston, Ohio, United States.

Built in 1905,[1] it was the home of one of Jackson County's leading industrialists, T.J. Morgan, and it has been designated a historic site.

By 1905, he had become sufficiently wealthy to commission the design of his home from leading Columbus architect Wilbur Mills.

The various structural elements combine to make the Morgan Mansion more architecturally significant than any other building in the city.

[1] It is one of three National Register-listed buildings in the city, along with the Clutts House, the home of another prominent mining executive,[2]: 793  and the Harvey Wells House,[1] the home of the city's founder.
