A gold rush is a period of feverish migration of workers into the area of a dramatic discovery of commercial quantities of gold. Several gold rushes took place throughout the 19th century in Argentina, Australia, Brazil, Canada, Chile, New Zealand, South Africa, and the United States. Gold rushes helped spur permanent non-indigenous settlement of new regions and define a significant part of the culture of the North American and Australian frontiers. As well, at a time when money was based on gold, the newly-mined gold provided economic stimulus far beyond the gold fields.

The first significant gold rush in the United States was the Georgia Gold Rush in the southern Appalachians, which started in 1829. It was followed by the California Gold Rush of 1848-49 in the Sierra Nevada, which captured the popular imagination. The California gold rush led directly to the settlement of California by Americans and the rapid entry of that state into the union in 1850. Successive gold rushes occurred in western North America, gradually moving north: Fraser Canyon, the Cariboo district and other parts of British Columbia, and the Rocky Mountains. One of the last "great gold rushes" was the Klondike Gold Rush in Canada's Yukon Territory (1898-99), immortalized in the novels of Jack London, the poetry of Robert W. Service and films such as Charlie Chaplin's The Gold Rush. Resurrection Creek, near Hope, Alaska was the site of Alaska's first gold rush over a century ago, and placer mining continues today. Other notable Alaska Gold Rushes were Nome and the Fortymile River.

The Victorian gold rush, which occurred in Australia in 1851 soon after the California gold rush, was the most major of several Australian gold rushes. That gold rush was highly significant to Australia’s, and especially Victoria's and Melbourne's, political and economic development. With the Australian gold rushes came the construction of the first railways and telegraph lines, multiculturalism and racism, the Eureka Stockade and the end of penal transportation. Many of those involved in mining in Victoria later traveled across the Tasman Sea to take part in the Central Otago Gold Rush, New Zealand's biggest gold rush. This kick-started New Zealand's economy and made the city of Dunedin a major financial center in the young colony. In South Africa, the Witwatersrand Gold Rush in the Transvaal was equally important to that country's history, leading to the founding of Johannesburg and tensions between the Boers and British settlers.

Gold rushes were typically marked by a general buoyant feeling of a "free for all" in income mobility, in which any single individual might become abundantly wealthy almost instantly. The significance of gold rushes in history has given a longer life to the term, and it is now applied generally to denote any capitalist economic activity in which the participants aspire to race each other in common pursuit of a new and apparently highly lucrative market, often precipitated by an advance in technology.

Gold Rush! is a graphic adventure game released by Sierra Entertainment in 1988. It was designed by Doug and Ken MacNeill. Players move a man from screen to screen, and type in simple commands to control him.
