The Coeur d'Alene, Idaho, labor riot of 1899 was the second of two major labor-management confrontations in the Coeur d'Alene mining district of northern Idaho in the 1890s. Like the first incident seven years earlier, the 1899 confrontation was an attempt by union miners, led by the Western Federation of Miners to unionize non-union mines, and have them pay the higher union wage scale. As with the 1892 strike, the 1899 incident culminated in a dynamite attack that destroyed a non-union mining facility, the burning of multiple homes and outbuildings and two murders, followed by military occupation of the district.

The Silver Valley is a region in the northwest United States, in the Coeur d'Alene Mountains in northern Idaho. It is noted for its mining heritage, dating back to the 1880s.
