The National Museum of Natural History on the National Mall in Washington, D.C. was designed by the firm Hornblower & Marshall. It was meant to give the Smithsonian Institution more space for collections and research. Congress authorized it on June 28, 1902, and it opened on March 17, 1910, though the text says it was not fully completed until June 1911.

The article calls the style Neoclassical and gives no materials. The building has 1.5 million square feet (140,000 m²) overall, including 325,000 square feet (30,200 m²) of exhibition and public space. It cost $3.5 million. It was the first structure on the north side of the Mall under the 1901 McMillan Commission plan.

It joined the National Register of Historic Places in 2023. The infobox lists 352 staff in 2023, but the text says the building houses over 1,000 employees. It is a natural history museum with free admission, open 364 days a year. The article gives no hours.
