The Clinton DeWeese Firestone mansion was a historic house on East Broad Street in modern-day Downtown Columbus, Ohio.

The mansion was built for Clinton DeWeese Firestone, founder of the Columbus Buggy Company, which at one time was the largest manufacturer of light buggies in the world.

The mansion became a symbol of his successful business, with elaborate architecture and unique red terracotta trim.

[1] The house was completed in 1887, during a time when Romanesque Revival architecture was popular in Columbus.

The structure became offices for the Buckete Union Casualty company, operating there until 1960.
