Santiago E. Campos United States Courthouse, Federal courthouse in Santa Fe, United States.

The Santiago E. Campos United States Courthouse is a Greek Revival building on Federal Plaza in Santa Fe, New Mexico. Its walls are rough stone from the Hyde Park area of the Sangre de Cristo Mountains, with quoins and lintels of dressed stone from Cerrillos. The original 1853–1889 block and a 1929–1930 addition are linked by a two-story vestibule with a cantilevered stairway.

Construction started in 1853 as a territorial building but was delayed by money shortages and the Civil War, finally opening as a federal courthouse in 1889. A major addition in 1929 expanded the structure significantly while respecting its original design.

Six landscape murals by Santa Fe painter William Penhallow Henderson, completed in 1938 as a Works Progress Administration project, hang near the north and south entrances of the original building. Henderson co-founded the Santa Fe Art Colony and helped popularize the Pueblo Revival style.

The courthouse sits in downtown Santa Fe and is easily accessible on foot, with good space around it for viewing from outside. As an active government building, be aware that security rules apply when entering.

A sandstone obelisk at the main entrance honors Christopher "Kit" Carson (1809–1868), a veteran of the Mexican–American War and the American Civil War. It was erected by the Grand Army of the Republic and unveiled in 1884 before a crowd of about 5,000 people.
