Chimborazo Hospital was a Civil War-era facility built in Richmond, Virginia to service the medical needs of the Confederate Army. It functioned between 1862 and 1865 in what is now Chimborazo Park, treating over 76,000 injured Confederate soldiers. During its existence, the hospital admitted nearly 78,000 patients and between 6,500 and 8,000 of these patients died. This mortality rate of between 8.3 and 10.3 percent is among the lowest such rates of period military hospitals.

After the war, the Hospital became a refuge for freed slaves.

In the early days of the Civil War, most people did not expect the conflict to last more than a few months, so the Confederate government failed to immediately establish many kinds of necessary military infrastructure, including medical infrastructure. Many soldiers were sent to civilian houses to receive medical care, resulting in both unsatisfactory care and the illness of many caretakers. Most Richmond-area military hospitals were not purpose-built buildings, but rather repurposed existing structures, including warehouses, hotels, homes, and stores. These facilities quickly became overcrowded, and Samuel P. Moore, the new surgeon general of the Confederacy, needed to quickly identify new potential hospital sites.

Simultaneously and coincidentally, on an undeveloped plateau on the east end of Richmond called Chimborazo Hill, slaves began building a permanent winter quarters, including soldiers’ barracks, officers’ quarters, three hospitals, and a bake house. Since most Confederate soldiers would be wintering further north, Moore decided to convert the barracks into a hospital, appointing Dr. James B. McCaw, a professor at the Medical College of Virginia, as surgeon-in-chief.

The name Chimborazo is said to have been inspired by the volcanic mountain Chimborazo, in Ecuador.

Record keeping at Chimborazo Hospital was meticulous. There were ninety hospital wards, which all had shingled roofs, wood-plank floors, and whitewashed walls (interior and exterior). Each side of each building had three doors and ten windows; each window had a white curtain. Each ward was warmed by a wood stove and lit at night by a single candle. Each ward measured eighty by twenty feet and contained approximately forty beds. In addition to hospital wards, there were also bake houses, kitchens, ice houses, a soap house, a stable, a guard house, a chapel, a bathhouse, carpenter, blacksmith and apothecary shops, and five dead houses. Each building was surrounded by wide avenues, as McCaw believed fresh air was a medical necessity for recovery.

McCaw established a strict formal organizational structure, including divisional hospitals, surgeons, assistant surgeons, acting assistant surgeons, stewards, ward masters, nurses, druggists, cooks, dentists, and matrons. All surgeons were required to have at least five years of medical experience. Other positions were filled by soldiers, free blacks, slaves, and white women. For most of the war, even when the wounded from the nearby Seven Days Battles required tents to accommodate overflow, food was sufficient and medical care received praise. However, as occurred at all hospitals of the day, available resources were not always sufficient and sometimes organizational structures broke down, leading to insufficient care and an unsanitary environment. Soldiers who died at Chimborazo were buried at Oakwood Cemetery.

As news arrived of Robert E. Lee's retreat from the Siege of Petersburg on April 2, 1865, patients began to leave voluntarily or be evacuated. McCaw surrendered the hospital the following day. Some Confederate wounded remained as the Union began to bring their own wounded into the hospital; Union and Confederate soldiers resided in separate wards. By early summer, all patients had been removed.

Shortly after the buildings were vacated by the military, freed slaves began to occupy the site. While the 13th Amendment had freed all slaves in the United States, it had not provided work nor land nor housing for them. The Freedmen's Bureau, formally known as the Bureau of Refugees, Freedmen and Abandoned Lands, had been established to provide such necessities to freed slaves, but the bureau was limited in its successes due to insufficient resources, diverse and complex responsibilities, Presidential obstruction of bills to expand the bureau, and Black Codes restricting black movement, labor, and rights. The refugees remained segregated from society.

The Chimborazo refugee camp, referred to as the "Nation's poorest of the poor," proved a major logistical challenge for the Richmond city government, particularly because the camp's white neighbors often complained about the camp and sometimes incited riots. Chimborazo was just outside of Richmond city limits and thus offered little protection from their neighbors, leading to the formation of a militia (Richmond soon expanded its city limits to encompass Chimborazo). The major violent incidents came in March 1866, which were initially characterized by local media sources depicting the conflicts as "Negros" terrorizing defenseless white people. However, it was later realized that white men had been harassing and threatening the community, leading to several arrests, though all but one were released.

In response to the riots, the Freedmen's Bureau ordered all able-bodied men vacate the camp by April 1.

The City of Richmond gradually began buying up the land of Chimborazo, gradually removing all of the structures and beginning work on Chimborazo Park.

Today, the land of Chimborazo Park is owned by both the City of Richmond (27.9 acres) and the federal government (5.6 acres).The park contains several monuments, including a smaller version of the Statue of Liberty and one commemorating the relationship of Powhatan and John Smith, and a museum and visitor center, the headquarters of Richmond National Battlefield Park, which is primarily focused on Civil War-era battlefield medicine. The surrounding neighborhood has been nationally designated as Oakwood-Chimborazo Historic District.
