The O. C. Barber Colt Barn, built in 1912, is an historic farm building located on Austin Drive on the Anna-Dean Farm in Barberton, Ohio.

It was built by American businessman and industrialist Ohio Columbus Barber, the developer of both Barberton, which he envisioned as a planned industrial community, and the nearby 3,500-acre (14 km2) Anna-Dean Farm, which he envisioned as a prototype for modern agricultural enterprise.

Barber was called America's Match King because of his controlling interest in the Diamond Match Company.

[2] It is one of the smallest barns on the Anna-Dean Farm and was first called Bull Barn No 2 and used to house bulls until 1913, when it was renamed the Colt Barn and used to house colts and mares in foal.

[3] On October 9, 1974, it was added to the National Register of Historic Places.
