The New Almaden quicksilver mine in the Capitancillas range in Santa Clara County, California, United States, is the oldest and most productive quicksilver (i.e., mercury) mine in the U.S. The site was known to the indigenous Ohlone for its cinnabar long before a Mexican settler became aware of the ores in 1820. By the time they were identified as mercury, the mine was perfectly timed to supply the California Gold Rush. The mine ran intermittently after 1927 and eventually closed. It was purchased by the county and is now part of Almaden Quicksilver County Park.

Cinnabar, bright red mercury ore, was used by the Ohlone people for paint. Andres Castillero, a captain in the Mexican Army, obtained a grant to the mine in 1846 but, occupied with his military duties during the Mexican War, soon sold it to Barron, Forbes Company, an English textile firm based in Tepic, Mexico. It was named "Nueva Almaden" by Alexander Forbes. Castillero's mining claim was confirmed by the Board of Commissioners that evaluated private land claims in California on January 8, 1856, but there was continued litigation in the District court, The United States vs. Andres Castillero. A claim of fraud was made on behalf of the Quicksilver Mining Company, which had acquired a competing land claim originating in an agricultural claim to the land the mine was on. On appeal to the Supreme Court of the United States the claim was found invalid in a decision rendered March 10, 1863. One of the competing land claims was Rancho Los Capitancillos.

The mine is named for a mercury mine in (old) Almadén, Spain, which had operated since at least Roman times. The term Almadén, meaning "the mine"., is derived from the Arabic language through medieval Islamic Spain.

In 1863, acting on information that title to the mine had not been proven, Abraham Lincoln attempted to seize the mine, but the federal agent and deputy federal marshal were met at the mine gates by armed miners. Mindful of the possibility of losing the loyalty of California during the Civil War, the federal government backed off and Barron, Forbes Company was allowed to sell it to American investors for $1.75 million.
