Mother's Building, Historic Italian Renaissance building at San Francisco Zoo, United States

The Mother's Building is a single-room structure designed by architect George W. Kelham in Italian Renaissance Revival style, built in 1925. Its exterior has a red Mission tiled roof and five arches with Corinthian columns and pilasters. The loggia side walls carry mosaics by the Bruton sisters, and inside, wood paneling with carved flower details frames four egg-tempera murals of Noah's Ark scenes.

The Mother's Building was built in 1925 as part of the Fleishhacker Pool and Playfield, commissioned by brothers Herbert and Mortimer Fleishhacker and dedicated to their late mother, Delia Stern Fleishhacker. It served as a lounge for mothers with small children, with restrooms, nurseries, clinical rooms and tea; boys over six were not admitted. The adjacent wading pool was removed in the 1940s and replaced by a children's zoo by the 1960s. The building was listed as a California Historical Landmark and on the National Register of Historic Places on December 31, 1979, and as a San Francisco Designated Landmark on September 16, 2022.

The loggia's side walls carry mosaics by Alameda-born sisters Helen Bell, Margaret and Esther Bruton, made for the Public Works of Art Project, showing Saint Francis of Assisi with animals and a panel of children with animals. Inside, four egg tempera murals of Noah's Ark scenes, begun in 1933 and finished in 1938, are by Helen Katharine Forbes and Dorothy Wagner Puccinelli for the Federal Art Project.

The building is currently closed to visitors due to seismic safety concerns. It is located within the zoo grounds, so access is dependent on general zoo operating hours.

The building served as the zoo's gift shop and visitors center from 1973 until 2002. It is the only remaining structure of the Fleishhacker Pool and Playfield complex, and its interior Noah's Ark murals, begun in 1933, have faded and deteriorated partly because of the nearby ocean.
