The Argo Tunnel is a 4.16-mile (6.69 km) mine drainage and access tunnel with its portal at Idaho Springs, Colorado, USA. It was originally called the Newhouse Tunnel after its primary investor, Salt Lake City mining magnate Samuel Newhouse, and appears by that name in many industry publications from the time period when it was constructed. The tunnel intersected nearly all the major gold mines between Idaho Springs and Central City, and is the longest such drainage tunnel in the Central City-Idaho Springs mining district. The mines along the Argo Tunnel are no longer active or maintained, but continue to exfiltrate ground water. The drainage from the tunnel was a major source of pollution in Clear Creek, until the U.S. Environmental Protection Agency (EPA) began treating it with a facility, built near the tunnel entrance. Large drainage tunnels in other mining districts include the Sutro Tunnel on the Comstock Lode in Nevada, and the Leadville Tunnel and the Yak Tunnel at Leadville, Colorado. The associated gold ore mill is open to public tours. As of 2017, the tunnel's front portal was re-opened to the public and included on the tour circuit.

The Argo Gold Mine and Mill is a former gold mining and milling property in Idaho Springs, Colorado, featuring an intact gold mill built at the entrance of the Argo Tunnel. The tunnel was built between 1893 and 1910 to drain the gold mines in Virginia Canyon, Gilpin Gulch, Russell Gulch, Quartz Hill, Nevadaville, and Central City and allow easier ore removal. The success of the tunnel as an access route meant that a large volume of ore began exiting at the Idaho Springs entrance and a large mill was built to process it. At the time it was one of the largest such tunnels and milling operations in the world, directly recovering nearly $100 million in gold (11.2 million ounces) valued in 2023 at $10.1 trillion. They also sent another $200 million of high-value ores to smelters in Denver.The property was closed in January 1943 after a major hydraulic accident in the tunnel, and never reopened after a federal moratorium was placed on gold mining during World War II. In 1976 it was purchased by a local investment group led by James N. Maxwell, who wanted to preserve an example of the Colorado gold rush mines. It was renovated and reopened as a tourist attraction and mining museum, and presently continues to offer daily tours. It was added to the National Register of Historic Places in January 1978.

Idaho Springs is a part of the Denver–Aurora–Lakewood, CO Metropolitan Statistical Area. As of the 2020 census it had a population of 1,782. Idaho Springs is located in Clear Creek Canyon, in the mountains upstream from Golden, some 30 miles (50 km) west of Denver. Founded 165 years ago in 1859 by prospectors during the early days of the Pike's Peak Gold Rush, the town was at the center of the region's mining district throughout the late nineteenth century. The Argo Tunnel drained and provided access to many lodes of ore between Idaho Springs and Central City. During the late twentieth century, the town evolved into a tourist center along U.S. Highway 6 and U.S. Highway 40, which ascend Clear Creek Canyon through the historic mining district. The town today is squeezed along the north side of Interstate 70, with a historical downtown in the central portion, a strip of tourist-related businesses on its eastern end, and mostly residences on its western end. It also serves as a bedroom community for workers at the Loveland Ski Area farther up the canyon. The town today is the largest community in Clear Creek County, but, for historical reasons, the county seat has remained at Georgetown.
