Wendell Lewis Willkie House, Historic residence in Rushville, Indiana, United States.

The Wendell Lewis Willkie House is a 2.5-story brick structure with a slate roof and stone foundation located on North Harrison Street in Rushville. The building displays Italianate architectural features including arched window openings and decorative brackets that define its exterior appearance.

The house was built in 1874 during a period when Italianate style was fashionable in small American towns. It gained historical prominence when it became the residence of Wendell Willkie, a political figure who shaped American life during the mid-20th century.

The house is also called the Cullen-Mauzy-Willkie House after its first owner, judge William A. Cullen, and the Mauzy family, who owned it from 1924 and ran grocery and general stores in Rushville since the 1860s. Willkie revised and corrected his book One World here after his wartime world tour for Franklin D. Roosevelt.

The house stands on North Harrison Street in Rushville, Indiana, and is a private residence, not a museum with regular opening hours. A separate 1.5-story frame Book House was added to the grounds in 1984 to hold Willkie memorabilia. Anyone wishing to see the interior should contact local heritage groups in Rush County beforehand.

Willkie revised and corrected his book One World inside this house; he had drafted it in New York after a world tour undertaken on Franklin D. Roosevelt's behalf. A 1.5-story frame bookhouse added to the grounds in 1984, matching the Italianate style, stores memorabilia relating to him.
