The 1855 Harris-Kearney House is an historical site located in Kansas City, Missouri, in the Westport neighborhood.

[3] This Greek Revival mansion was built in 1855, and was owned by Col. John "Jack" Harris and his wife Henrietta.

In 1846 the Harris family purchased a business called the Catfish House located at the northeast corner of what is today's Westport Road and Pennsylvania.

This new, grand hotel was considered integral to the neighborhood as it provided food and lodging to explorers, trappers, Union soldiers, gold miners, salesmen, politicians, and pioneers traveling west on the Santa Fe, California, and Oregon Trails.

[5] In 1921, Elmer Williams, a businessman, bought the Mansion House and wanted to demolish it and build a hotel.

The Westport Historical Society acquired the home and property in 1976 [2] and restored the exterior to its pre-Civil War facade.
