Colorado Governor's Mansion, Government residence in Capitol Hill, Denver, United States.

The Colorado Governor's Mansion, also called the Cheesman-Evans-Boettcher Mansion, is a late Georgian Revival house of red brick with white wooden trim under a hipped roof with gabled dormers. Its west portico has two-story fluted Ionic columns, and the entry columns support a porch that becomes a balustraded second-story balcony. A semicircular sunroom added in 1915 overlooks Governor's Park.

Denver architects Willis A. Marean and Albert J. Norton designed the house, built in 1908 for Walter Cheesman's widow and daughter Gladys, who married John Evans II that November. Claude K. Boettcher bought it in 1923 and hosted President Eisenhower in 1952. The Boettcher Foundation gave it to Colorado in 1959, and it was restored in the 1980s.

The mansion is named for its three families: Cheesman, Evans and Boettcher. Claude Boettcher, who bought it in 1923, was known for lavish parties; President Dwight D. Eisenhower attended one in 1952. The house passed to the Boettcher Foundation, which gave it to the State of Colorado in 1959.

The mansion sits at 400 East 8th Avenue, on the southeast corner of 8th Avenue and Logan Street, beside Governor's Park. Tours are free but run on a set schedule, so book ahead through the Governor's Mansion website or the governor's office; larger groups should arrange a time in advance.

The mansion was built in 1908 to house two families: Walter Cheesman's widow and her daughter Gladys, who married John Evans II, grandson of Colorado's second territorial governor, that same year. The semicircular sunroom was added in 1915 at Mrs. Cheesman's suggestion and overlooks Governor's Park.
