The Hales Mansion is a mansion built in 1916 in the Heritage Hills neighborhood of Oklahoma City, Oklahoma, United States.

The Second Renaissance Revival house^[2] was built for William Taylor Hales, a prominent business man of early Oklahoma City, in 1916 at a cost of $125,000 USD. In 1939, the mansion was bought by the Roman Catholic Archdiocese of Oklahoma City and served as the residence of the archbishop until it was converted back into a private residence in 1992. The mansion was added to the National Register of Historic Places in 1978.^[3] In April 2017, the mansion was bought by an Oklahoma City radiologist for $2.125 million.

The house contains 20,021 square feet of living space spread over three floors, and an additional 3,136 square feet of basement,^[4] making the Hales Mansion the largest residence in Oklahoma City. The mansion was designed by the firm Hawk & Parr and is constructed of Bedford limestone and bricks imported from Greece. The main entrance on the east facade is a large, two-story portico supported by eight Corinthian columns. The secondary entrance on the north facade, facing the Overholser Mansion, is also a two-story portico but supported by four columns. On the ground level, the main entrance opens into a grand hall and a grand staircase.
